I love the direction of the E icon. Do you think it would look better if the inverted E and the outside border of the graphic were more delineated, so the E pops more?
I don't like the "ENCOSIA" text as much though. I'd like to see something different there.
I love what you did with #81. Can you tone down the highlight at the bottom a little? In both #26 and #81, I wonder if it would look better with a little less indentation into the back of the E at the top and bottom? Or maybe a more rounded back to the E, to contrast? I'm not sure; just ideas.
For the main text, I'd like to see a font that's less rounded and placed horizontally beside the logo.
