The "W" and how it looks like a stick figure is creative +1.
I like the combination of this color dark/gray its easy in the eye, do you think you can come up with a different combination of colors? the blue one is just too blue.
Maybe green and blue (earthly feel)? or maybe just blue period but not as bright
look at the
www.worldcoinfoundation.org maybe similar to that kind of blue, not as bright.
What do they look like in small size?
