Obviously, I still really like #39. It's been towards the top this whole time. It is a logo that simplifies well. Now that we're getting towards the end of the competition, I'd like to see #39 with a little more "pop" and color effects to it. See what you can do to make it a little more fancy. Gradients, contour, shadows, lighting, etc. Whatever you think would look good. You're the designer, you know better than I do what looks good.
It is really coming down between #39 an #18 for me.
