Those are pretty good. Much better than anything I could do.
Metal Gear Rex and a Power Suit guy wielding a laser rifle? Dude, that's excellent artwork. The shadowing is brilliant, and the second piece really captures the movement of the soldier. Nice work!
My only critique would be that some areas are a tad too dark for my tastes, like you just went crazy with shadowing. Still though, no detail is lost, and they are dark subjects to begin with...
Great job, man. Keep it up!
Whoa, didn't notice this one.
Yeah, I'm with Tacheon on this one about the shading. Plus, your proportions are nicely spot-on, especially for Metal Gear REX.
