it seems like a floating head to me. but i really dont know what the render is so it could just be a head. and some1 else said it needs more depth and i agree. its good but could be better with some small lil tweaks. and maybe blend the render with the bg a lil bit more? thats just my .02 cents but overall good work keep it up.
Yea Yea Loving the smudges here man nice flow imo It does look like a floating head thou xD I had the same problem until local made me come to terms with it
