A wee bit of background information:

So, I was browsing trough my downloads, and noticed this picture, which I liked very much, but which had gif artifacting. So I decided to clean up those artifacts, and ended up tracing the original outline of the image, and just blurring the areas around the lines to smooth out the shading, and thus reducing the amount of the artifacting. While I think that the blur made the shading too smooth, in that the image could have more sharper highlights atleast, I didn't want to go too overboard with the aftertouch.

Never the less, I couldn't find any method of contacting this "Tapdon", who seems to be the original author, but I feel that since I only did the tracing, the original artist should be marked as the author, and I wouldn't mind getting his/hers blessing for having this up here.
