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.
Thank you,
April
