Firstly, what's new? Is everything upgraded? i.e. clothes, armour, furniture, items, environments etc or just specific parts?

Secondly, does it look better or as good as Skyrim HD 2K which I currently have installed? I assume the new textures would overwrite these.

Thanks in advance for any info.
