I really like aspects of both #90 and #104.
I think I may like the orange background in #104 best (but I'm not entirely sure yet).
Of the two inset graphics, I lean toward the "e" in #90, but I think it's a little bit too complex. I'd like something simple and bold that people will be able to remember easily, if that makes sense. #104 is a good example of that, but not quite what I'm after. Something with that simplicity, but still focusing on the "e" would be great.
