Continuing the discussion from Submit your logo design:
This is great realization of the idea I had in my mind from the beginning, but since I am not versatile in graphical design, I simply left it alone. I am glad to see that someone else also came to this idea. IMO it looks great!
However, I would suggest to create a version with only top layer (the green one) and the yellow base; loose the “dirt” part all together. In that way it is completely in the spirit of the MC, while it is true to its physical model upon which you have based your design.
