I like #19 a lot better than #24. The green on #24 is too bright and I like the glossy look better. Also, I think we should stick with the letter casing of "myhELO" or "MyHelo". I know I said it could be anything - I just had to see it a couple different ways to know what I liked.
The word "hELO" is too bold in #34 and #35. We also want to simplify a bit, so it fits us better to go with something more flat instead of 3D. Maybe we go back to something like #24, but use the better colors and possibly a slight gradient.
