Well this was pretty cool! I like the idea too. The eyes, the forehead, the main thing here: looks great. The teeth, hmm, not sure... surrounding bone roses seem a bit simple compared to the big one too, and it bothers me a bit that it's not fully centered, even though the canvas is ALMOST square. But really cool composition overall.
I'm imagining this as a wallpaper now... in a house. The floral patterns of old come back with a vengeance...
