I showed this to my brother(who doesn't know about ponies) and he thought it was some kind of dragon. And I just said "LOLNOPE, this is a pony motherf*cker!" (That's actually what I said. Then he hit me lol)
It really reminds me of the Inheritance Cycle (which began with Eragon, if you don't know), with the picture of the dragons head facing the viewer. This is kind of what I imagined Galbatorix's dragon looked like, though it was never shown on a cover.
This is just so sick, the way his eyes burn into my soul and his nostrils and maw flare with fire.
This is my first critique, so I apologize if I do something wrong. This is an excellent picture; very detailed and striking. Those eyes reflecting evil are just indescribable. And that breath coming out of his mouth is amazing, Although I give it four stars in originality(because i've seen several pictures in this style), I must confess i would give it ten stars in impact and vision if I could. Picturing Discord as a real and evil threat contrasts with the real one, but this is a really interesting approach. This is one of the best pictures i've ever seen in my life. Great job!!!
