The first two (#9 and #8) are too obviously Russian for us. Please give us something with architecture from another country - perhaps the Czech Republic and Prague? Design 3 is too corporate for us and it invokes space travel, which is not what we do.
We are concerned about the overly Russian look of cupolas. Can you try one with something from Prague? Just google Powder Tower Prague - it might work perfectly with your logo design. Thank you!
