What does this mod do exactly?

With this mod, you can choose from 19 textures for each of the following dragons:

1. Dragon
2. Blood Dragon
3. Frost Dragon
4. Elder Dragon
5. Ancient Dragon
6. Odahviing

Do you want the frost dragon to have the skin of an elder dragon or Odahviing to look like a Brilliant Leviathan? Well, you could have renamed files and done all that stuff manually before, but now you can do it with a few mouse clicks in NMM, and you get a preview of what your dragon will look like.

This mod does not have textures for any of the expansion dragons (revered, legendary, and serpentine). Perhaps in a future update I can add them in.

Please check out the attached images for a preview of all the textures offered by this mod.

How is this different from the HD Dragon Replacer mod?

The HD Dragon Replacer mod has no options, i.e. the default dragon texture is replaced with a modified dragon texture that is true to the original.

The HD Dragon Replacer includes modified textures for vanilla dragons, expansion dragons, and Alduin. This mod only includes the modified textures for the vanilla dragons. No legendary, revered, serpentine, or Alduin in this mod.

How is this different from the New Dragon Species mod?

New Dragon Species added new dragons to the game and didn't affect the default dragons. 

This mod just adds the new textures so you can use them in place of the defaults.
