Hi Therre!
First please take a look at the 2nd ranked logos key. It is thicker and it looks better this way. In the future please stick to the thicker keys.
Secondly, please check these keys.

Thirdly I would like ask you to, somehow get rid of the "H" letter's upper curve line.
Thank you in advance.
Regards
Attila
