These are great, thanks. #26 is better, but unfortunately now I see "horns" - sorry. #27 is good, but we are struggling with the square - it doesn't feel elegant enough - but I'm not sure why (same goes for all the entries with a square boxy graphic. I really like #28, but the font feels a bit "chunky" to incorporate the pen in the "A" - it's a really nice idea though. We need the whole composition to feel elegant.
Thanks again!
