Nom nom!! The pink one is still my favourite, it matches the style you're going for brilliantly! I do like that bright green one as well though. I can see that on a cocktail bar sign. The red one on a diner, ahh they're all good! The bottom one though I think is too sharp for what you're doing, maybe even too sci-fi?
These are exciting Druzga!!!! I agree with Emma i still love the pink one, especially the one with the reflection. The green one is also a nice contrast :)
