Need a bit of help (Dunno where this goes honestly)

well for one thing you have a lot of nasty jaggies most noticeably on the hair. to clean up remember to do diagonal lines in fixed intervals unless a curve is intended.
the bottom of this image should be a good enough example

Man, oh man. That's gonna take a long time.

Yes, curves are intended, but I doubt they will matter once I reduce the size of the image.

Once I reduce the size will be where the real clean-up starts, I think.
