2 but I don't think any of them are quite there yet. The shapes for the B isn't working properly. I like the idea of bring two shoes together to form the B and also depict a heart shape but it is not instantly recognisable as a 'B.' If you didn't tell me the brand, I would of thought it was called 'ellaneri.' I think you need to revisit the shape or maybe include the negative spaces inside the letter 'B' to make it clear. Or use some colour to kind of outline the B and match it with the rest of the letters.
Just out of interest, what font is that? It's lovely.
Number 3 looks more shoe like than the first 2, but then again, it also looks more like the view you'd get looking down at a girls chest .. I'm not keen on the font either. It reminds me of the font you'd find on an Indian takeaway leaflet. I'd like to offer something constructive, but can't really. It's far from finished. Did your designer show you anything else?
