I agree, your colors are wonderful, but you need more contrast in value and design of fabric. Looks like you got off to a good start by using a focal fabric for your color scheme. But you ended up with two relatively large paisley prints and two prints that are nearly the same color and value. A geometric print in place of the darker paisley would give you more variation in design. Contrast in value can be determined with a value finder or a black and white photocopy of the fabric.
Anxious to see your results.
Happy stitching and Happy New Year
