These are pretty and classy. Let me run them by the office folks. Overall though, I am looking for a more vintage/retro vibe. Happy to provide you with any feedback that could help. Just ask. Check out our facebook page and the profile too. Might help you with some ideas to see behind the scenes.
I love the style of your most recent entries. I would definitely leave them up as they show a lot of diversity. I don't think we can go with dolphins, but really, it's a beautiful logo. Thanks you for the efforts you put into our tournament. I enjoyed seeing your designs and I wish you well.
A note from a client's point of view. I don't know why the designers yank all their designs if they aren't chosen. It's really helpful to look through peoples portfolios and I think keeping some of them out there for other customers to see will help you get more clients. Just my opinion.
