Looks a little fuzzy to me. Yep. Just checked my glasses and they're clean. Hmmm...maybe this is more focused than I thought but not where it needs to be? The upper-left looks good. The front center doesn't.
I think with just a bit crisper focus/deeper DOF this would score a bit higher. It appears just a tad soft in places, and the more interesting "swirls" are on the edges.
