I think it is beautiful just as is. If you are wanting more of a contrast and get a louder wow factor I might use a solid or a fabric that reads as one color of dark blue. The dark blue you used has a lot or lighter blue in it and it calms down the contrast and lowers the wow factor. Hope I am making sence to you. Try using a ruby red viewer to test your fabric because your preference may be to dramatic quilts. Hope this helps. Gail
