Very good first try! But overall you denoise too much and lose a lot of details because of it. You have to save it as JPG on max quality too.

Beelzebub: You forgot to burn the letter H on the vending machine.

BD: Good.

DGM: You forgot to burn some spots. You also removed the gutter shadow the wrong way. Use a quickmask to select the gutter shadow and level it.

FT + DD: Over denoised, otherwise good job.

Reborn: There are still marks of merging. You forgot to burn some spots here too. Greys here are also over denoised.

Naruto: A little bit blurry. Good.

Fix those and you should be able to get in very easy. Good luck on next try ;)

Well, with over denoising I mean that the grays are ruined because of it. You lose too much detail. The marks of merging is those black line you can still see.

The link you gave only has reborn, the sendpace one too.

Can you upload it to mediafire please? MU is giving me "The file you are trying to access is temporarily unavailable." at the moment ><

Edit:
Can you please redo all of them? Without ruining the grays.

All the pages except blaze drive.

Beelzebub: Good, you just have to burn the letter H on the vending machine.

DGM: Over denoised again, you lost the pattern in the grays. Please redo this page and be careful with denoising.

DD: Good except for the grays, they are over denoised again >< You really should lower the settings while denoising, you're over doing it.

FT: Good job. You didn't over denoise this one.

Naruto: Good, just remove the text in the last panel and fix the page border in the top left corner.

Reborn: Could be denoised a little less, but this is acceptable. Good job on the merge. You forgot to burn some blacks, like hibari's box weapon. Also remove the dusts on the bottom right corner. (it should be completly white)

Restart with the DGM and DD page, these aren't fixable.
Good luck on your next try, I hope this helped.

Heya! These are looking pretty good!:

Beelzebub - Good. Done!
DGM - I can see you're trying to denoise less on this image, but the result puts that weird denoising texture into the grays, rather than actual halftone patterning, which you really can't get from the raws anyway. That said, I think you had better results with version 3 of this one. Keep the bottom half of test 3 but redo the middle box at the top of the page. Look back at the raws and try to imagine what this panel *should* look like. It really should be a softer gradient, fading away at the bottom. Then just do what you need to do to make it look like that, be that redrawing or denoising or what have you.
DD: Much better grays. Incorporate the details you lost from version 3 (like in the eyes) back into the image and I think it's done.
Naruto: Good. Done!
Reborn: Good! Though you darkened Yamada's weapon instead of Hibari's! (Hehe, don't read this one, do you?) The blacks he was referring to are on the inside of the spiky thing in the upper left. Otherwise it's good.

Almost done! :D

Awesome, with those changes I think you're good to go. They all look really great. The next step is getting you confirmed with Devils, the head of the Cleaners!
