The colors of all the fabrics are good together. I think the problem is the middle two have the same size/scale designs, so they don't play well together. If you eliminate one of the center two fabrics you should be good to go. If you need four different fabrics for your pattern, substitute another tone on tone fabric in one of the colors represented in the top large scale fabric, maybe a t.o.t. red or a t.o.t. dark green.
