Original scan somehow got damaged, see painted areas on Saki's highlights on arms and Nodoka's right blushlines. I believe it wasn't fireattack's drunken rampage, and in case it was aftermath of fixing creases, I didn't find any proofs that there were any; and definitely that wasn't artist mistake, however I could be wrong about it. There's a white spot on psp, don't know what that is.
Removed dust and dirt, restored, cropped.
Fixed with GIMP. Please recheck .
