I think the crown is kind of silly looking, even though it's carrying the theme from the shoulders (which don't look that bad).
I get that they are trying to make a reference to the Lich King, but it looks like one of those cardboard Burger King crowns you'd get as a kid.
It wouldn't be so bad if it didn't stand out so much. The color could be more subdued, maybe even like an Iron Crown.
hmmm.... clipped the points off the crown, added a single 'gem', darkened the whole thing from that obnoxious gold to a more subdued grey/brown.
Looks better to me.
