The "Lich" looks more like one of those hobos you find looking through garbage-cans, wearing piles of rags and pushing carts full of trash. He is overly complicated in design for the sake of being overly complicated. And its distracting.
The color palette is disagreeable and not aesthetically pleasing
The Lich has two left wings
If the lich wasn't there, it would bean uninteresting background that has been done a thousand times before by better artists.
