I really like the abstract design and the motif that says "express." We are trying to avoid using an extracted tooth as our logo. I would like to see other variations not based on an extracted tooth. A motif that says smile, comfort, or simplicity might work.
Very nice. I really like the combination of fast & smile with the smile shaped arrow. I just feel like it is missing something. It is not completely clear that it is supposed to be a smile. I know it is because I asked for a smile, but I'm not sure if it is clear to the casual observer.
I still like #9 the best, but I feel like something is missing. I like the concept of making the logo look more like a badge with a shaded bounding area like the Facebook logo.
We really like #106. We did like the text better from your other entries (for example #16) with only the first letters capitalized. Can you rework #106 with the text like that?
