Beelzebub: Good! =D
BD: Flatten the grays a bit. (You can do this with topaz clean) also sharpen the grays a bit.
DGM: Really good job on those grays!You overburned a bit on the hair. If possible, sharpen the grays here a bit too.
DD: You mustn't remove text outside bubbles, but you can leave it like that for the test. Nice job.
FT: Same as DD, could a little sharper.
Naruto: Sharpen this page a bit too. (or just the gray panels, these are really blurry)
Reborn: Remove the little dust left on the right bottom corner. Good merge.
Fix those and send a PM to devilsadvocate101 with your application, he will take over the application. You have to spam him though, or else he won't reply XD
Good luck ;)
