About five minutes ago I submitted my rendering of a photograph of another artist's clay model. Then I removed it after another deviant got upset that I hadn't added a link to the original.

Fair enough.

Only, that got me thinking: if I wanted to submit it again, would that mean I'd have to ask the original artist's permission, even if my rendering is in fact a digital drawing and not a clay model?

I'm genuinely interested, because I think, having put in the time and effort to render the picture in a different medium, that I should still have creative commons to put my picture up without feeling like I've copied or cheated from another artist.

....
Thoughts?
