@Paul - re: Lovecraft, same here. I used to read a lot of his stuff but haven't done so in years. It was great fun. I'll have to dig out some of my old books out and re-read them.
@Mike Mc - re: censoring, if I had any authority, I agree with you that there are almost no works of art that I would censor (meaning prevent others from accessing them).
However, I certainly don't hesitate to voice my opinion on a piece, and I always reserve the right not to take a job.
@Clare - IMHO, you're certainly taking it in the right direction - a reasonable compromise - but I still think that there is a strong visual and emotional clash between the subject and mood of the new background. If I were to work on this image, I probably would extract the two subjects, move them apart a bit to give them some breathing room, try to complete the backs of their heads (which are currently cropped away), leave the skin color as I currently have it, but decorate the background with Harry Potter / wizard-related toys / props and a setting that is happy and appropriate for a child's Harry Potter themed party (eg, kids on brooms riding around in the sunlight, kids costumes (

In fact, if the OP had stayed with his original request,
"...I dont want their faces changed at all, just that background, and possibly the text at the bottom...", I wouldn't have especially agreed, but I would have had no major problem with it, and probably would have helped him. However, when he switched to,
"...Yes! Only I'd like to color their faces like the poster does...", that's when I decided I didn't want to work on it.
Cheers y'all,
