Well, there are a few things that could be considered flaws. There's the red pixel that was already mentioned. The dragon legs are a little too large and they aren't bent as much as the rune. The black parts at the ends of the legs are reversed. You left out the hole that should be at the crotch. There's a stray pixel on the right leg at the knee (left leg if you were wearing them). That's all I can find.
