Very beautiful, but I only gave it a 5 because it didn't fit the guidelines for me (Abstracts are about lines, shapes and colors. If it is recognizable as an object - it is not an abstract)
Ordinarily I would critique the blurred foreground but in this case the pale blue-grey blends invisibly into the white background in a pleasing way. The soft focus and light value contrasts nicely with the sharp focus and dark values.
