its ok, the feeling of the render, it just doesnt look like he belongs there, like its not right for him, the effects are really nice though, your current is way more awesome =D
not bad i dont like the rende ron the right i think u could hva eblended it more in, its kinda in ur face whereas its just the backgorund, also the left side is blured which makes right right stick out even more if u get me.Just work on the backgorund i think andit would look a lot beter.
