Great designs! Something about the blue "TL" in the box in #17 doesn't suit me right. Can you try just a T or something else? What I really want to incorporate into the logo is just the hint of a shark fin or gill, but I would like it to be so subtle that you can't really be sure if it's really a fin. It may be impossible to do it and still have a stylish logo, but I think it might be possible to have a very classy, subtle fin somewhere.. or is it a fin? Anyway, just an idea....
On entry #75 (which I have ranked #1) can you adjust the line underneath it so that it is narrow on the left and thicker on the right. I do not wan the line any thicker, I just want to see it more narrow on the left side, similar to the logo I presently have raked number 2.
