Scene looks awesome!!
Thanks! 
Awesome composition, you really got an eye for that.
I am very impressed by the daring compositiion, including the way that you sent one of the diagonal rays through the skeleton’s eyes, then past his hand on the same [sight …] line. It’s also interesting that the skeleton is “partly skinned.”
This is the sort of bold graphic art that I would expect to find on a concert poster for a rock-and-roll concert that I would really like to see. 
The only constructive suggestion that I might add is that the lower part of the skeleton’s torso (from the bottom of the rib-cage down) essentially disappears altogether. Perhaps an appropriately-shaded dim fill light covering that area – but affecting only the figure, not the background – might be worth contemplating. Or, for something visually more bold (and possibly contrasting with the gradient now used for the background), what about a complementarily-colored (and upside-down) gradient for illumination along the figure?
Thanks!
