#38 looks clean, but it reminds me of a street and therefore a tire company. I like the colors and how clean it is, though.
#40 has better colors. Again, the white line is questionable, as is the position of the clouds. I think this one has potential, but I'm not sure exactly where to go with it.
#39 — We want to avoid using the text as part of the logo.
Thanks for the new submissions! I really like the colors in #54 but I'm still not sure that's a good final concept. #55 has the right idea, but looks kind of raw and incomplete.
Hmm...something about that green section in #70. I like the colors, but I wonder if it could be used to represent something. Not sure what, but I'd like to see some variations of that green area. Really starting to like this one :)
