Well, it was a boring day, and i made a promise... That's the result.
My GF hands used as base, highlights from dark blue to light blue, with a little freehand. Not my best freehand but she was rather happy!
We put some transparent nail paint to cover the acrylic, and apparently the acrylic works as a "solvent tank", so you need to wait an hour or more before all is really dried. However, it was an interesting experience.
