EnvirosphereLogo Design Contest

I like the simplicity and colors. The one thing I would like to see changed is the color choice for "sphere" in 9 and 10. I would prefer blue to gray.

I think we can exclude expanding work on 11 and 12. I think I would like to keep the colors down to 2 in the logo and three in the whole design.

Thank you very much for your feedback.
I send the change requested and also a version without the vein on the leaf, so it looks less environmental.
Please let me know if you want to see any other change or variation.
Thank you,

Thanks Carrion. I appreciate your interactiveness.

Could you try 5 through 8 with the line removed as well?

Versions without the line.
Thank you.
