Awesome piece so far! I think your biggest problem here is that all your values are too similar and that is what's making things look muddy. I've marked a couple of spots that might benefit the most from some highlights to both accentuate our undead dragon boi and those blasts of ice in the foreground. The ice might also benefit from sharper divisions between highlights and shadows along with more texturing. Hope this helps! | Artwod Feedback
