...yeah...what they said ^^
Anyway, there are some grey dusts here and there (especially in the third panel). You might wanna get rid of those. However, this page is already overlevelled, so you might want to get rid of those by "coloring" them. And, like they said, the old borders have to be erased, and new ones have to be redrawn. You also might want to resize your page to the proper sizes.
Other than those stuff, pretty good ^^
