You said to be nice--right? WOW!!! I think you did a super job of setting the blocks and can't find a thing wrong. If you want to try feathers, can you get some thin paper like tissue and draw the feathers on that, then pin it on your top and quilt it? Or if you can make a template that will have the outline of the feathers, you could mark that on your top with a removable marker and add the feather lines from that? Not sure how clear that is, but best I can do so early in the morning.
