Very awesome work, though I have a few critiques. His head is...oddly shaped, though that may just bethe angle's fault. Also, the grenade gun would be the same color as the rest of the armor, I have to assume, since it's attached to the thing.
I have a few other nitpicks, but I feel I'm being a dick enough as is. Sorry, but Steelhooves is my favorite character, and when you see something you love done, you nitpick the hell out of it.
Oh oh! Critique! Thank you so much for the critique!! The head is shaped how it should be, but the angle of it really does throw you off. As for M-19 Launcher it was not standard issue with his original Power Armor, meaning he just found this somewhere to be a sufficient replacement, not only that but if it were the same color as him it would blend too well. ^^
I would still love to hear any other concerns you have with it! I'm always looking to improve ^^ and never worry about offending, i can take critique! aaand in case you haven't noticed I really enjoy it! Steelhooves is also my favorite character! x3
