Personally, the glow doesn't bother me, because it is very slight, but I do agree on the plastic sort of looking textures. However, the quality of these pictures still aren't comparable to what we will see on a tv or PC screen, especially in motion, and especially on my Nvidia 460. I think we'll have to wait before we can declare anything about the final product.
Even then, its practically a given that modders will create textures that make us wonder why Bethesda doesn't hire them.
You still haven't seen the game in motion yet. Everything looks better while its moving and also, you say the characters hand is "glowy". Well obviously, don't you notice he's casting a spell? He appears to be channeling magicka through him and also, fire gives off light.
You didn't look hard enough at the skeleton picture. Their bodies have a slight glow effect around them from the light. Its very obvious on the right most skeleton.
