Hello....
some good ideas you have going:) I'm going to give you some feed back/suggestions, from my view...hope to help:)
Logo 1.....while the idea is good, the logo looks scattered, not pulled together..
maybe fade the E & D? tweak the baselines? meke the viewer 'get it'...right away.(I'd make the E & D evolving into the square and dot more pronounced, )
Logo 2
probably my 2nd favorite(I'd make the bands of color, more varied, the ED color, brighter?)
Logo 3
To me, the wispy font (scriptina), and the sketched look of the logo, doesn't convey evolution, maybe more modern looking/edgier...? for a consulting group, great idea.....
Logo 4
the font, the border, it comes off looking a little , well, boring, again maybe get rid of the border, different font selection, try a rounded corner box?)
Logo 5
I like variation B......again I'd further explore variations, the font in volution.......this has a lot of potential
very good concepts:) let us know what ones the client chooses, or revisions you make, its fun to see a loge evolve(

:)) into perfection:)
