Hello Ivan and thank you for joining. Here are my comments to your work :
1. #14 I like very much. please use a white background, because we like to use the logo on different backgrounds. In the absence of a better alternative i like our current font style very much. the "y" in the current way is something not fount very often. maybe you try to get a little bit closer to the current font style.
I also like the gradient (font) in entry #12, but we print mainly on color laser printer - so printing result is also a great deal to us.
