hi Clément, and welcome!
i was away in the weekend, and i guess there was a misunderstanding about the deletion of your post.
Your offer is truly appreciated, and i like the clean style of the logos you created.
Anyway, i think having just the Earth as icon is not distinguishing. The current icon (hand holding earth) is nothing new for sure, but a step further in this direction (self-made with two googled pictures).
