Excellent, I'm glad!! Thanks again for the commission! Since you ordered with GC you didn't get the terms I hand out but all copyrights to the art are yours to use however you want, I only reserve the right to display it for my portfolio. 
Ah, well I just posted it as a thumb on my profile so if someone clicks it, it'll go to your drawing xD
Hehe I've had people ask me if its OK to use art I made for them for icons and such and I'm like its all yours you can do what you want with it! hehe. But I'm glad you used it for your profile!
I don't see why they wouldn't be able to use the art since they paid for it and such, what would be the point of getting art if you can't even use it on your profile or icon? Like hanging it up on a wall but online xD like of course with crediting
I totally agree, but maybe some artists are weird about it, idk.
