I like the simplicity of #34, prominence of "Vector" and the play on color in position (blue on bottom of large V, complimented by "Vector" on top, and vice-versa for green). I'd like to see a greater energy in the visual, perhaps a three dimensional effect. Alternative color combinations might unlock the strength of this design.
This is my first LogoTournament and I'm just learning how the rounds work, so I apologize for not getting you feedback sooner for you to participate in top 5. You have a great portfolio and I would have like to see more.
