MtG = Magic the Gathering, known for it's quite epic illustrations for a CCG, at least more epic then every other CCG.
Seriously though, do have that in slightly bigger? I'd totally love that as my background, that's how awesome it is (as pretty much all your illustrations imo). I actually like how that, I guess it's a dragon, dragony thing isn't in the focus. It kind of doesn't give the eye something to rest on but I think you actually pay more attention to the picture that way, unlike other things on the art portal that are like "look here's something to look at and some crappy-to-decent background".
I could go on interpreting but that's tl;dr anyway so yeah. 5/5 from me =)
