Interesting in that you are kind if the only one of our strong early candidates who took the "at the core" idea and used it in the logo. That's a nice catch! For starters, we actually like the two-version method yours offers us, lets keep that going as we might be interested in a multiple-version final product. Try orange or another color. And keep the "outside / inside" idea going, but maybe more architectural and less like a target / bullseye? Terrific font choices. Don't be afraid to have the "icon / playful moment" of the logo happen somewhere other than the beginning of the logo, too. Thanks for a great start!!
