Good job for the most part NTM_. The only thing that I think could of been done better, which can be a difficult and tedious thing to do, is Pain's Rinnegan circles on his right eye. They look uneven, and some of the circular lines seem to overlap each other. Also, the pupil seems to be blurred, making it look like Pain is looking into 2 different directions. It's something you only notice when comparing both eyes, so it's not to bad. If you're good at doing small touch ups. Try to make the lines, and the spaces inbetween look more defined, as well as even. If you do that, Pain's rinnegan eyes, as well as everything else will look almost perfect.
