Without meaning to sound negative, Im not sure that the type works. To me it doesn't say nail salon. I feel its a bit too bold and bulky where I would imagine what you are trying to convey is elegance etc???
Also I think the hand is a bit obvious, as someone stated above.
If I were you I would perhaps brainstorm what I am trying to portray and try thinking of how the imagery can be 'dfferent' ie span off from hands, nails etc?? Also consider how this would look when scaled down for use on different media, business card etc, the hand would lose a lot of the detail and definition
I think the colour scheme is really nice and you have a good start, sorry if I have seemed harsh but hopefully constructive??
Good luck with the design
