I've got no worry about trademark infringement, I design all my own stuff. However, I have read that if you make 7, or more, changes to a trademark, it is then considered your work. Don't recall where I read this, possibly on the patent and trademarks site. I once used a photo taken in about 1914, of an individual from one of the NorthWest tribes, to use as the face for my cigar store Indian bank. Later figured out I had made 11 changes from the photo - all hand sketched.

.....Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
