your fabrics are lovely.
i did notice though they seem to be all about the same.
alot of time in order for a quilt to work is by the (VALUES) of the fabrics chosen- the colors really have nothing to do with it- you can use any and all colors- but the LIGHT-MEDIUM-DARK values are what make the quilt work-
for your final fabric i would try to find something to contrast- (make the quilt pop) if all of your fabs are medium try adding a dark= or a very light
