I dont know about him and weather he's new to it or not. But I've been learning graphics and I find the best way to learn things is to look at other peoples work and make my own version of it. Like Madwolf's State puff marshmellow man from ghost busters. Granted his is infinitly better the one I made was pretty good considering I did it from scratch while looking at his work for examples. I might post it some time for more help on what I should do in the future.
So rather than insult some one because they use your work and modify it. You should first check to make sure they arnt doing it to try and learn how to make graphics. I would think as long as they arnt trying to use it for something it wouldnt really matter. Not like the servers that rip your graphics and claim it as there own work.
But then again I could be way off track and have missed something.
