There is no depth 2 this really and the colours could be better i recommend taking away the lighting or put more of it on his face because right now there is a patch of light the effects are cool just try bring ryu out more and blend him not cover him with the effects thats not much help but the render looks more like a cartoon and there hard 2 do Keep practicing and i am sure you will get alot better Keep it up : )
i get so confused with depth can some 1 lead me to a real easyto follow good tut for depth i will +rep and send credits if u want
