The dwegar has two problems with it, both can be overcome.
First is that the animated part of it, one of the meshes starting with X, is still pointing to earlier textures. You need to go into NIFScope and point to the correct ones.
Other problem is that one side of the head is darker, even if you tweak the texture. Fine in a darker place, but it really shows outside in the day.
Even so, it is a wonderful creature and worth using. I will be doing some dark retextures of it later on, but not for a while.

http://rapidshare.com/files/379411602/DBTextures.7z

There are really amazing resources in that TC. Lots of plants, lots of creatures, lots of just about everything.
