I like design 22 better than the first ones you did, but I'm still a bit bothered by the snow - I'd like it a bit more clean.
Would love to see #25 with different colours - but keeping some part of it black. Also, when the logo is small, the letter C in castle looks a bit like a G - not so much when its large though.
I like #23 - can you discard the banner look on the bottom of the logo and just square it off? We're definitely leaning towards a logo with some colour black within it.
