Thanks for submitting your designs. On #149, the text needs to be larger. I like the designs that have the text and logo at about the same height. The blue/black color combination is interesting. I can't decide if I like it or the blue/green better. They both look good.
I'm soliciting feedback from trusted friends and family, and many have mentioned yours are one of their favorites. In addition to wanting larger text more in line with the logo, I would also like to see a more "squared" font. Something similar to Arial or Tahoma in style. I think the "E" looks out of place currently on designs like #149.
I'm pretty sure I like the color scheme in #225 the best. The colors in #235 seem to "playful" to me. I like what you did to "solutions" in #237 & #238.
