I read your comment after the contest just ended. That's a great idea about the glow. It can be done but I'm afraid that detail may get lost when you scale the logo down, say on a business card. I usually stay away from gradients when it comes to logo design. Sometimes, you can run into problems when you go to press at the printers if you utilize gradients. However, on the web, it would translate really well. You could even animate the logo for the web so that it glows in subtle, tasteful way, of course!
I just love the simplicity in
#138. It was actually my first sketch when I started brainstorming and led to my other designs. Thanks for all your feedback, I appreciate it!
