Just a wee little update...
Started drawing some of the supporting characters... kind of like in Metal Gear Solid, you've got a support team back on your mothership. Although this game will have much more streamlined dialogue than Metal Gear
One thing I hate is when it takes a half-hour of reading text to get to the actual game.

From left to right:
Hacker, Weapons expert, Mission commander, Science Officer.
I'm already reconsidering some of these designs... the commander looks uncomfortably similar to Jill Valentine and the science officer is probably gonna bleach her hair.
Oh, there's nothing wrong with looking like other characters. You could even mark it down as an homage, rake in some nerd cred from the people who like the character.
I also like the variety here a lot, especially the hacker. He looks like a real weirdo and I always do love the weird ones!
I'd try to vary up the girls a bit more though, there's a lot of difference between the hacker and the weapons master both in terms of complexion and body build yet the two girls are only really differentiated through their clothing and hairstyles.
It'd make sense to give the Commander a bit more muscle, since that's a very physically demanding job!
