They are all gorgeous. As presents to friends and family, they would be greatly treasured
However, when selling., one thing I have learned is the need to differentiate from those who mass produce stuff and sell it for less than you can buy the materials. In the right circumstances with folk in love with Quilting they could do better than otherwise, but in designing generally one has to reach farther than going where the software leads, Really beautiful results can be achieved, but those who mass produce stuff will do the same and they can flood far more than you can. Even doing cleaner work with greater perfection will be a lot more work that will not be noticed unless it is extreme and you build a name for that extreme
All that said, I have not found a great answer for myself, and perhaps have pushed too hard trying to push that envelope, and those designs as framed art, boxes, and coasters that anyone seeing that look knows it is you might be the real success plan.
