Very cool looking. Unfortunately, over time the resin encasing the skulls will move differentially from the surrounding materials with temperature and humidity changes, and require repeated work to keep the surface finish looking seamless.
I made the same mistake years ago when I embedded a silver wizard casting in clear resin. Cool for a while, then pain in the ass after that. That's not a criticism of the design OR the maker; I think the design is mega-cool and it looks well made - it simply won't remain pristine over the test of time.
On the other hand, future finish maintenance may be an acceptable trade-off for the impressive visual and visceral effect in the eyes of the maker and owner.
