I -had- to get myself warmed up.. So I practiced drawing EVERYONE'S FAVORITE REPLOIDS. This is the result. I remember Zero giving me hell, when usually, it's X whom is my pain in the ass to doodle out. O_o;; My mind is awkward that way. Zero and Axl are easy, because of all their details, (like, Axl's strips on his armor) help me remember where everything else is. Axl and Zero have ALOT of intricate details, while X, in his standard armor, is rather plain. Because of X being a plain looking chara, my mind has no "roadmap" of how everything is on him.. So therefore I struggle alot with X. however, I'm noting, I'm getting alot better drawing X... And Zero is getting harder.. Axl, still relitivly easy. o_o;

I think you did the best job on Zero, though! I like how you can draw the vent thing in his chest... I STILL have no idea how to grasp that, as simple as it may look
and the shading on his armor is very subtle and corresponding to the light source. moogly!

I have to say, you have a really solid grasp on the charas... I agree with Flowery, the Zero "vent" looks just great. The only thing their boots being wider in height and X's hands, but these are minor quirks. The drawing's very pleasant to look upon.
And you also got Axl's hair right! I hate his design because of that. That hair ALWAYS kicks my ass... >_<
