This are one of my most recent nail designs. I've recently been getting back into a Sesshomaru kick (from the anime Inuyasha for those of you who don't know) and so this came out of it.
The middle nail has a silver tip for the color of his hair and a blue crescent moon as it is the symbol on his forehead (go look up a picture, you'll see what I mean!) The other nails are based on the pattern of his clothing.
Unfortunately I didn't keep these for long; I smudged them beyond repair after applying the top coat and moved on to a new design.
