On, the left, the Teenage Mutant Ninja Turtles as drawn by IDW artist Ross Campbell.

And on the right, the work of Damon Bowie, as sold on eBay and his website.

It's interesting, Bowie is clearly an accomplished artist and the work does have a rather polished appeal. But it appear to be derived from Campbell's originals, don't you think?

And some of his other work on the website also looks a little familiar… can anyone identify the originals in question?
