This is beautiful. Everything compliments everything else. That little peak of yellow is strong enough to jump out as not fitting in, yet subtle enough that the green still has a presence and the viewer can figure out why. That is the brilliance. The pattern is obvious when you see the green, but for me I only see the green because of the yellow.
I like this shot a lot, and the shadows at the bottom, but because none of the clovers are level it puts shadows all over the shot which is pretty distracting. Maybe a different angle of organizing the clovers differently could help
