Some archive photos from last year when I just got my camera so I feel that I overrated the ISO and these are taken in a quite dark room which make them blurry. But, since then I've learned.
Anyhow, this is a nail art I've done similarly before (see HERE and HERE). I've used a blue and purple glitter polish and one blue polish and another purple polish and black fineliner. And mattified! I really like this mani and I assume I'll redo it more times too.
