I'm with Jo on this, your art is wonderful, but zone 3 needs to be blended in better and could be thinner.
Also if you look at the way the light reflects of your nails you can see where you need to file a little bit more to really achieve a smooth finish.
But I truly admire you for doing this, I'm not sure I'd be brave enough to try it and I'm dam sure if I did they wouldn't look as good as these:hug:
