I can see the black background all around him, you might be able to use the magic wand tool to fix it though... Not bad for your first try.
I redid the render (Kakashi) agian to take the black background off... i dont know if it looks better, but you can decide... :unsure:
it's good but little choppy. BTW. What feather did you used at making selection 0px or 1px? My advice for future is to use 1px feather when making selection ^_^
i agree with the others. a lil choppy, but still nice. heh, but the render has been done alot. i did it once. hm, don't use the wand when rendering. add a layer mask, and use a black brush to render it. i always do. takes a while, but it's real smooth in the end.
the quality of the render could be better, and its choppy in some areas, and i think the head protecting thingy is on the wrong eye =/
