The "lens" and the "hand" on the #15 caught my attention, but i really don't understand the "half-dot" over. Something more colorful seems to be better. Don't worry about the slogan right now.
Hello Dasx, i really like the #15, but we can not change some things that are important to me. I would like to use this logo on diferente colors, but i dont like any other versions you made. May you want to try a last one? there is time! :)
