Well basically the quality was realy bad. At first I didn't see it on my laptop screen but later on my PC screen I saw it was very bad. If you check for example this picture (in your high res version):
you see that on the bottom the black and his pants are just really really bad. In most cases, 200 or 300 kb for a 3000x2000 is bad quality I think. Did you compress them with PS or something?
Anyway some Sweeney Todd are uploaded by another user now in a better quality.
