I've been planning on drawing chibi Mass Effect characters since the second game but the characters never turned out right but with the third game out and Troodon80's references I decided to open up those chibis again.
Of course, I had to draw Female Shepard and Thane first but, like BlueLagoon4 I'm gonna try to add new characters to the pic every week or so.

Characters So Far:
Added 3/10/13
Male Shepard is finally in the picture. He's based on my textbook manager from the Mass Effect Too Soon picture I drew last year. He was very pleased at my drawing of him! Also I added an awesome background. I really wanted the Illusive Man's but that was proving far too challenging and I was running out of time, this tutorial really helped with the sun, [link]
The space background and starfield came from another tutorial by [link]

Added 2/9/13
Javik has finally been added!

Added 12/9/12
MY COMPUTER IS ALIVE!!! A week off of drawing fanart is horrible!?
Kai Leng and James are officially in the picture and as pure some requests Kai Leng has a box of cereal? James was surprisingly super easy to draw for me. Anyone else think James looks like a juice head version of Puck from Glee?

My mini shadow broker characters are complete! Tela Vasir and Feron are now included! Feron is in his comic book outfit b/c it's ugly but it's uniquely his! Vasir is ready to charge someone!

The Shadow Broker. He took WAY longer than I thought he would...He is so weird to draw. I made sure I drew him extra big b/c he is a HUGE guy. I still laugh when I see my lil' femshep in a punch out with him.
I'm glad she has confidence but did anyone believe femshep could really go toe to toe with the shadow broker?

Added 10/3/12
Shiala from Mass Effect 1. I got into an asari thing and I drew a whole bunch of them and I remembered lil green Shiala on Illium! Not technically a villain but you did have to fight her to get to the next point of the game. I just realized, she fought Commander Shepard...and LIVED!! I need to give her her props!

Added 9/26/12
Ms 'Don't f with Aria!' Aria is now in the pic. I know she isn't a villain but she is definitely renegade and could probably take over the galaxy if she wanted

Added 9/21/12
The first villains of Mass Effect Saren and Benezia! I changed the background to red and blue b/c now it looks like the villains are going to be making their appearances. Oh no! That means I have to draw Kai Leng?! NOOOOOOOO

Added 9/5/12
EDI is in the pic now! I actually drew EDI first but it didn't seem right that Joker wasn't drawn at the time. Her color threw me off but I think she turned out adorable!

Added 8/29/12
Finally got around to submitting Joker. I'm kind of bummed out that he didn't become a romantic option in ME3. Oh well... I decided to draw his chair because Joker standing up is just weird, he need's to be in his leather seat
Added 8/22/12
The Illusive Man, gotta admit one of the few men that has nice hair in the mass effect galaxy.
Added 8/15/12
Yeoman Chambers is now in the pic. Another character that ticked me off that she had bangs and my shepard barely has a strand of hair for bangs

Added 8/8/12
Finally added Legion! Someone recommended me to draw Legion doing the robot and because I also had a complete drawer's block on how to draw Legion I went ahead and drew him dancing with his lil' head pieces up.
"Shepard-Commander, this unit has it going on!"
All the Mass Effect 2 squad members are present and accounted for!

Added 7/25/12
Samara and Morinth. I was going to draw Morinth in her normal outfit but I thought it looked better if she wore the black version of Samara's outfit. Personally I like Morinth better in my pic, but I haven't saved her once in all of my files.

Added 7/18/12
Zaeed Massani!

Added 7/11/12
Kasumi Goto, the best but not the the most famous thief in the galaxy! I'm kinda disappointed Kasumi and Jacob didn't hook up, which is probably why I went ahead and positioned her next to him.

Added 7/4/12
Happy 4th of July to all!
Grunt has been added! Why WHY couldn't Bioware give me Grunt as a party member!!! Mass Effect 3 feels empty without a Krogan!

Added 6/27/12
Everyone's favorite psychotic biotic Jack! I am so upset I let her get possibly killed because I didn't realize that Grissom Academy mission will become unavailable...I didn't think I was going to like Jack in ME2, but I'm a sucker for tragic backstory and also Shockwave was really super SUPER awesome.

Added 6/19/12
Mordin Solus - He is the very model of a scientist salarian! Seriously that scene in ME3 made me want to pour one for my Salarian homey!

Added 6/7/12
Miranda Lawson - Everyone's favorite big bosom Cerberus Officer. I like Miranda, maybe because I have a close relationship with my sister and Miranda is such a good big sister.
Jacob Taylor - I really REALLY wanted to like him but Thane overshadowed him so SO easily.

Added 6/05/12
Urdnot Wrex! My absolute favorite character from the first game!

The original Party Members of Mass Effect 1 are all in the picture!
Thane is special though that's why he was first!

Added 5/30/12
Crystal Shepard (NOT default Femshep, mine has blue eyes) When I use her in the game, the pyromaniac achievement is never far away. Hehehe
Kaidan I love his voice actor but Kaiden you are making me wish I picked Garrus for Crystal Shepard!
Ashley Williams (Don't mess with her she's got her boomstick out and she's not afraid to use it!)

Amaya Shepard
Thane Krios
Garrus Vakarian ( I am not a Garrus fan but DANG I LOVE how I drew Garrus here!)
Liara
Tali Zorah
