When I was a kid, I used to trace cartoons and comics.
All kids that want to draw in a particular style that they find appealing.
It's a thing most people grow out of, as they A) learn that it does nothing to improve your own skills and B) you can't actually do anything with the "art" because it's still
someone else's work.
I say most people.
seems content to play photocopier AND is oblivious to copyright law, in that he's attempting to sell images that are clearly traces of VERY well-known artists.
I doubt he's the only one on DA doing this, and I have a special hatred for such vermin, so if you're aware of anyone else that is both copying other people's work AND trying to sell prints of the results without authorisation from the original artist - reply here with a link.
