we like #33. however, for the star part, try to change the gray color to the green color to see what it will look like (so the logo will have 3 colors in total). thanks.
also, from a distance, the logo looks a little like a american football. if there's a way to make the leaf look more like a leaf, that would be good. thanks.
Some confused thing here, i thought you want "american" look. Thats why i tried to produce my design arround the stars shape,to pop out the american feel. Please review all designs once more. Thanks.
