I think that the repeat is pretty close together and there won't be much variety between the colors or patterns in your wedges. I've done a couple of OBW's and I think they turn out best when there is a fairly large print with lots of different colors. The print needs to be all over, not too much empty background. Your fabric does have that aspect.
I'm working on a floral one now. It has light green, dark green, light cream background, pink, purple, blue, yellow, red, fuschia. It is going to be very full of contrast and variety.
