Don't worry I just wanted to point my view of the logo. When creating the moon I spent some hours until it looks cool, and that was the best I could do.
You said that the moon is unrecognizable. But when I tried to create the negative curvature it don't look cool, only if I add Earthligth effect it looks a bit better, but not there.
...(a realistic one always goes from north pole to south pole)...
That just completes what I'm talking above, the moon looks so strange that way. I can create the moon in 5 ways: full moon, realistic full moon(where there's a little part in shadow), first quarter, last quarter and new moon(not total new moon, but a ending last quarter).
What are the problem: last quarter and almost new moon make the moon almost invisible, there's too much dark side.
Full moon(realistic) look too strange you need to force the imagination to see that it's a moon. It looks more like a drawing error than anything.
The only option stay at first quarter moon, but it looks a little too much dark side, but less looks a little strange. That's the point.
But your commentary was important for a new change, now I rotated the moon a little and now it's really better, also desaturated the tree, What you think: (Everybody can comment too)
Don't forget the moon phases are not comming from the earths shadow on the moon, but from moon's night side not facing the sun.
Don't worry I will remember.
