agreeing with maniac.
The third is difficult to critique without knowing how much might be subject to change. The color combination doesn't say salon to me, but if that is set already... what about the repetitive striping with the white... is that negotiable? If you need it, I would not use the horizontal one... only vertical.. and would suggest not having quite so many of them. also, I'd consider trying an asymetrical arrangement.. maybe even a progression of fatter lines & spaces, gradually transitioning to thinner ones... and only on one side... maybe just a more basic double strip on the other side... heck, my ideas might not look good either, but I'd be trying something different on that one.
My only other thought was to get into some node editing on the first Italian restaurant layout. If you can get the tails flowing from a preceeding letter to tie in better with the following letter, it would be worth the trouble... maybe on the second "p" I'd cut off that tail, and on the "o" I'd try to steal the tail off an "a" and get it to flow right into that "s". The other thought is in regards to the fade you have in those letters, and the stark transition from "r" to "i"...that makes me want to see it fade, but if you liked the second "p" with no tail, a stark color shift might look better (to me) between two letters that don't touch..
anyway, they all look good, but different tastes bring different suggestions, so it's great when folks ask & we can all see the variety of concepts...
