So, I've been working on this Ent model for awhile--call it a mild (insane) obsession =) I'd like to get it to photo-real soon by making some crazy textures (32k) and modeling a few interior rooms for the windows, but in the meantime, this deflector dish is killing me. It looks fake. Is there any advice how I can still make it look like glass/glowing without that 'CGI' look?

Thanks!
