For some reason your lovely artwork reminded me of church. It could have been the wrecked churches in the background, but I think not. Religion has had value I am sure but it has also been the cause of an equal amount of misery.
Wow, this is really well done. Kind of looks like the corpse tree from the movie "300" mixed with the forest of suicide from seventh circle of hell shown in the game and animated movie "Dante's Inferno."
