I honestly thought his eyes were all the way up on his forehead, I took a closer look, and saw he had his goggles up! Nice touch!

i dont want to criticize to much but the fingers look too pointy but, i love the pose. Seems unique thought.

hmm

Everything looks good, but the problem is the character is just so unnaturally positioned, most notably the right hand holding the sniper rifle. Its got detail, but really lacks life

dude don't worry

this is tankmen afterall so the gun might be like that

all you have to do is work on your proportions, otherwise it's pretty sweet.

I'm not

A professional at art and what not,
But you're work is great! One thing to work on though, and I'm practicing it myself too, is body proportions because the legs are just a little too small compared to the body, but practice and continue your good work!
Also the detail to the weapon is sweet.
Recommended to scout. :D
