Wonderful picture! I think the competition is steep for this challenge and this does not come across as "Odd" as you might like, but it's a GREAT picture! Great focus and DOF. Nicely done.
7 - Good and 'odd', I am sure the size restrictions don't do this justice. Criticism; want to say wish there was some sharpness around the edge of what looks like glass beads(?), but then you'd likely lose the focus on the refractions, so who knows. Nice colors and although the refraction idea is obviously not 'new', the multiple in almost symmetry may be yours, if so, well done. Maybe a slightly different crop on this, or 'composition' (if possible), especially to gain more 'symmetry', may have made this better in my opinion.
