These are great! I like the integration of the two letters in #1, #2, #3. The others you did were a little too abstract, and I don't think a person unfamiliar with us would see the AV in the logo. One of the places I will be putting this is on a silicone wristband, so I think I'll need it in a simple one color without the shadow under it as well as one without the words. Maybe also one with the words to the right of the image and next to each other instead of above each other (so it would fit on a wristband). I hope you'll be able to work with me on this if you end up being the contest winner. Thank you.
Thank you - I think entry #13 will be more functional for my purposes, although maybe I could use entry #4 on the web and #13 on things like the wristband.
