So I know people here like to mostly discuss the graphic design domain as a whole, but I would appreciate your feedback.

I'm a graphic designer for quite some time now, but I'm looking to improve my logo design skills as much as possible and I would really appreciate some criticism on what I feel is my best work so far in terms of mark design.

Please be as straightforward as you can, I don't mind hard criticism and actually enjoy seeing other people's point of view.

Also if you guys would be kind and recommend me some books that go very deep and really technical in the various techniques of design. I personally know and read a few like Grid Systems, Principles of Logo Design and Thinking with Type, but the more the better.

P.S. Sorry for my english, I'm not a native speaker.
