Feet and hands are just laziness and it would look better if it was sharp...In order to make it sharper (using gimp) you click filters>enhance>sharpen and presto...overall I'd give it a 4/10 and 600 value...w/sharpness 6/10 and 1K value...Great idea though
It's a little bit too sharp. But I like the simplicity, and I think you could've used more of that blue color that you used on the leg.
I also think that the style of the feet could match the head a bit more. The feet look a bit like camouflage and the head has a tribal feel to it.
All other than that it's pretty neat. 8/10
Looks pretty cool, maybe some more detail/shading, just to give it some effect. Also the hands and feet really need to be done properly. It has potential, but I'd rate it around 7/10.
Life is like Basketball. Aim, Concentrate, Balance and Following through. That's all you ever need to accomplish your goals.
