The Drago armor doesn't come with textures for the dragon, only the for armor.

The Millennium Dragon 2 has a black texture, and they appear to have the same UV map, so you could use those textures on the Mill Dragon 1.

Note that if you have the Mill Dragon 1, but not the second that there is an "Upgrade" version of the Mill Dragon 2 which is $20 cheaper.
