Thanks for the crits guys, I'll try to cook up an edit. Lemme address some issues:
I'll redo the letters to make them have no shadows, and the inbetween lines on all lines within the letter.
That's not me in the ref pic.
I see what you mean about the head/neck/torso. I think I will make the neck a little shorter and try to beef up his torso. Even though he is an alien he still has relatively human proportions. I don't want to mess with the face, because I rather like how it came out.
The thing about the difference in the should blades, is that one side is a rocket-launcher, and the other side is just a normal part of the armor.
About the colors, I like the monochromatics of it because it brings out an oldschool feel, but I am open for suggestions. Just as a note, Lennus, the creature, is brown, and his armor is olive grey, and the rocket is purple.
