Hello,
My first render ever.

C&C please.

lol
1) when you move the hands, rotate them too =/
2) same with the foots
3) try to make your own model... don't take foodeater one xD

^same as dae, but also, change up the lighting. Everything looks too... light. Less ambient occlusion.

^What they said, and also, (since one leg is forward and one is back) it would feel a bit more natural to have the chest rotated a bit.

the joints is too blurry, the texture below neck(forgot the name) dont have any texture with it, but its kinda cool 9/10

All of what they ^ said. Also, maybe change the camera position/rotation? Not bad for a first, to get a feel for things. Also, make your own models/background or something, it feels very bland.
