I like it! Cool textures above his head were the lines are! I like V2 better! Nothin really to say but there really good!!!
Not enough happening in the BG for me; if the pic isnt there then its just a load of fuzz. The pic should be complimentary to the background. Theres also a lack of flow.. i prefered V1 myself.
I like whats happening around the render and above it, but the rest is to plain. Prefer V2, but you still did a good job
