All the logo proposals are very good but my favorites are the logo of Hive account@gade4rt & the logo of Hive account@crittercrats since both logo proposals are very unique. Hive account@gade4rt for using the petroglyphs with elements and colors of nature as the fundamental basis of their concept and Hive account@crittercrats for adding a mask or face to the planet earth, together with elements of nature. I hope both are among the winners.
