Noob question - how can i fix that overlap?

Hi, I’m not a designer or anything, I just wanted to create some kind of a logo, and now i just can’t get this problem I’ve created out of my head :smiley: There is an overlapping on the last element of the “flower”. I’ve spent total of 2 hours trying to solve it but i just can’t. Can I rely on your support?
