You should've done more than just the carapace. I know the CL wraps abysmally, but still...
On a side note, could you update the screenie with a shot of the Carrion Beetle with this skin? It'd be nice to see how it he looks....
As for your animation problem: the Crypt Lord originally had Alternate animations (with his shell open). You can stop spells using these with one of the fields in Object Editor (I think it's something like "Animation Names", near the top in spell edit); just change the animation names or remove the "alternate" bits.
