It's fine. The point is, you'll do the right thing and take off the art that isn't yours and do your own.
I recommend GIMP to help you get started. It has taught me many things and advanced my learning in art. It's free, too, and similar to Photoshop; but yes, I'd recommend taking off all of these before Deviantart removes your account, just to be careful. You can still favorite all of the Ivy works on the site, though!
