Amazing colors! Tons of mood in this piece in the low lighting :)
Looks greatin gallery, but as a portrait I can't really see anything below the upper mouth, hard to tell that it's a warped skull rather than a normal one that was cropped too close. Could be partly differences in my monitor vs yours?
Cool blue glow too.
You used great colors and shading to really make this skull look worn and decrepit. And I love the gradient for the blue glow. Nice job.
lovely!
