They look fine to me. I'm actually looking foward to outfitting my Nord in daedric armor.
Rather than being able to smith daedric/dragon armor, I wouldn't mind if smithing stopped at ebony, and for the higher quality armor to be a quest reward or something found in a dungeon.
It's actually nice how you can make Daedric armor through the conjuration skill. I agree that letting smithing do it is weird. Also, Ebony is more than enough to play the game anyway, especially considering a smith of that level would improve it so much in the first place.
