Nice Job^^. You're very good for an inexperienced cleaner. However, your biggest flaw is that your aren't leveling correctly.
In depth examples:
page- 1 Looks excellent^^.
Page 2- the whites weren't leveled as indicated by massive amounts of dust on it. Blacks could use at itty bitty bit more leveling but its fine overall.
page 3- Good Cloning/redrawing :> Somehow it seems the page is overleveled on the whites. Your backs look fine, but some of the lines have a greyish quality which tells me that you probably overleveled to get rid of the dust. Although, when doing a dust check, there is still a quite a bit of pixels surrounding the art and this particular grey line on the bottom left corner of the page.
pg- 4
blacks are fine. white should be leveled a itty bitty more :>. The cloning done on the flower - is obvious, i can see the repeating of ridges of the clone tool. Not bad on the 4 - though you have a black line at the very right and a portion of the white line isnt connected. On the guy's jacket, there is a half circle of tan pattern where there should be a straight pattern. There is also a black and white line at the edge that wasn't cloned.
pg 5- again white should be leveled more. You also didn't rotate the page correctly. Good job on filling in the blacks though, it looks nice ;).
Mostly, work on your leveling and you're good to go,ok?
