So, the idea behind this is to draw every character in three different perspectives ("full" body, rather close, portray) in the final fight of a better ME3 ending. Of course the first ones will show my favorite squadmates: Tali, Liara and Garrus. The focus lies on the particular characters, that's why it won't show teamwork or anything (which is kinda stupid). I have to admit I'm not satisfied with this one. It actually was a lot of fun painting a pretty, well, destroyed Tali, but I somehow don't like how there is no real action - and the backgrounds are so bleh. I have one with Liara in the making and the pictures there are a bit better considering the action, but anyway.
To explain this: I believe the most realistic way portraying Tali at the end of ME3 is portraying her having a hell of a lot of trouble. She wears no armor, only her suit - and there are like a million reaper tech enemies. So what will happen? Her suit will definitely get disrupted at some point, there is no other choice imho. I don't say she will die. It's possible, sure, it's even likely, but if you can also just imagine her being badass and Dr. Chakwas helping her after the Reapers are defeated. So it's up to you what you want to see in this.
Left picture: I don't really like that one. Her posture is strange (supposed to look exhausted) and she looks lonely. I can't decide if that's good or bad since teamwork is essential on the battlefield. But maybe at some point they end up being alone because.... rainbow. I don't know - this is stupid. And yes, she is wounded.
Middle picture: In my head, Tali is a badass. Most of the time she seems rather quiet but there are situations where she gets pretty mad but... still hides it. After the events on Rannoch and seeing a bright future ahead if only the Reapers where defeated, I assume she would do anything to make it come true. And blasting a hole in a Marauder's head while watching him directly in his stupid face... well, that must be rewarding.
Right picture: Nothing more than a portray really. Maybe after everything is over and she can rest or in the middle of the fight. She is pretty messed up by now, her suit is disrupted, her helmet got some cracks, she's wounded, exhausted and her immune system probably goes apeshit right now. She will still fight as long as necessary. It's Tali, come on, she has a shotgun! Talking about that: I can't draw weapons. Oh man. The Garrus version is so horrible because of that shitty sniper rifle, haha.
EDIT: I just realized that she is left-handed on the left picture. Never forget, kids: Don't flip your canvas too often! I'm sorry for that one.
