#72 nice logo part. Perhaps thicker lines, less empty space? And we dont like the font. Definitely should at least be lower case. #68 is going into interesting direction. Needs more experimenting both with shapes and color scheme.
#107 is good. How about stylizing letters (similar to #88)? Also the whole "earthcape" should look a bit more accentuated. Would making central cross line somehow stand out with a different color (light blue?) work? Another thing you could try with the line is to make it integrate with the text (e.g. as in http://www.devexpress.com/)
will have to disconnect for a little while, but a quick note for now: I thought more about that extending part as an arch going above "earth" part and landing somewhere in "cape", maybe continuing into "a" - but whatever works better. Will come back to all of these a bit later.
