i very much like the style of it, but it's not easy to discern what you're depicting. i'd say the ground needs more shadows and/or contrast - something to make it look more solid. otherwise, i'd say it's useful and approveable.

Is good, but it can't be appreciated.
Try with more contrast and zoom.

Honestly, I don't understand the concept of the icon. Maybe just my perception.
