Not Working At All

First and foremost I am only taking credit for the coloring of this image. The line art was cropped straight from the MegaTokyo webcomic # 1008 entitled "Not Working At All" (hence the title). This particular comic was a comic cross over that Mohammad F. Haque drew for Fred Gallagher. They are the ones who have the rights to the line art, characters, story, etc. The only alteration I made to the line art was erasing some lettering at the top of the picture. Other then that all I did was color it. There. Am I safe from getting sued/banned?

I think this came out really good (especially considering this is the first time I tried shading a drawing in Photoshop) but that's probably just because the line art is so well done.

Photoshop, Wacom Graphire 4, 4-5 Hours

Edit: I uploaded a better quality image with credit text.
