I really like 48. Could you put a line on the perimeter of the leaf so that you close off the continent on the right side? Right now, it kind of looks like the leaf was chewed by an insect. I think a line would solve that.
Also, could you make the ecopia word a blue color and the worldwide wider and green? Kind of like what you did with the logo with number 3.
Could you make the green in number 31 a darker green? Thanks! We are close!
