like the 3rd the best on the white background - definately dont want it to look like marijuana leaves though...
I think the "UR" is bigger than others, and it's make it not balance between left and right. Your logo concept is simetry, right? I think if u want to make the "UR" (your?) strong u must do it in different way
Hahahaha! Same here! Is that for a marijuana company? lol. just kidding. anyways, i like the second one. best of luck!
