#51 - Good
#54 - I like the way you boxed the text but I'm not crazy about this mark. It doesn't "say" anything to me.
#55 - OK but kind of simple. Not a strong contender.
#56 - I LOVE the way you created this abstract mark and yet the star subtley pops through in the middle. Very cool. I'd like to see more along this line. What is the trapezoids were solid? Or are there other ways to do something similar? I like this direction a lot. But I think it can work without the "E" being treated differently.
#57 - not bad but not one of my favorites.
#68 - Hmm... good proportions and colors and font but I'm not crazy about the mark for some reason. It almos seems over-designed for some reason. Does that make any sense?
#35,
#56 and
#51 are my favorites of your bunch.
I keep looking at #10 and I like the colors in that one. I think it's because of the gradient. Perhaps you could try a version of
#56 with a little (just a little) bit of gradient in the mark?
Thanks for all the hard work! These are great!
