There are so many things that you can do with that design. It looks reasonably balanced now, even with the blank area to the right. It can stand alone. The beauty of this design is that the weight of the design seems stable enough to allow you to leave the area to the right alone or, if you wanted to put something there, the overall design would still balance. There are all kinds of things that could be done with that area if desired, such as initials, a logo, rain, an inlaid gold moon, or even a dog howling at the moon. This is the kind of thing that you could sell by itself at a bazaar or charge extra for adding someone's initials. If you are good at quick numbers, you could also charge extra for adding the telephone number on the back.
Looks good overall, with the exception of numerous point errors where elements partially bifurcate. Simply put, these bifurcations, absolutely following the flow of the scroll backkbone, should point directly to the center of the element origin within the scroll. In the case of the scroll you have drawn, if one follows the bifurcations to their implied end point, almost universally, the implied endpoints you have drawn hook around to intersect partway down with the outside line of the individual elements. If you have Sam's video on drawing scrolls, please review the section on point errors again. These are not huge errors, and are easily correctable.
