Welcome to PixelJoint! 
I was very intrigued when I saw this piece in the public queue.
The lighting and and palette give an ominous mood to the piece, and the design of the dark prince is pretty creepy, too.
Looking forward to seeing more from you! I think I came across your portfolio recently and I enjoyed going through your work - can't wait to see how that would translate into pixel art. 
This is very scary
I like it
