Nice ideas, but as I mentioned, the skyline needs to be mirror-inverted, so the tower for logos no12-no15 would need to be on the left side. Thank you. The shape of the tooth by the way is better but still could be a bit changed.
The shape of the tooth in your logos needs still a bit of work. I like no22 and 23 but the tooth looks mor like a heart or a bum :-) The other logos would look better with a more stylish tooth-shape. But still good work. Thank you.
Much better! The grey only a tiny little bit lighter, please use big letters for the names, vertical liness in between and the letters less thick. Thanks
