Ref #24 - I like this, but I'd like to see more color and something that really stands out.
Ref #30 - Great design and concept. I don't think it relays as much of the "tan" concept as I need. It's definitely got the botanical element, but the tanning element needs to be strong as well.
Ref #47 & #48 - I like the leaf over the "i", but I'm not fond of the spine-like quality of the curve. Also, see my comment as to #30.
Overall, I'm looking for something with an edge that really captures one's attention and has both a strong tan and botanical element in the design.
