Just looks like the krausen settling down. But if in a few days it starts to look more white and the floaters have less of a sheen (like little white lily pads) then I would start to worry. Otherwise I think it is fine.
My issue is, that would be a 90%+ attenuation. That doesn't seem normal to me. My last beer was the same way with the same yeast and it wasn't a drain pourer but it was very one dimensional. The yeast is US-05.
Is it extract or all grain or partial mash? If it involved a mash, then lower than targeted mash temps could cause a more fermentable wort that would attenuate more resulting in a lower FG.
I thought about that when I put this recipe together bcuz of the last beer. It's all grain and I mashed at 154F for an hour. It's a blonde but I was willing to have a little more body if it wouldn't over attenuate. That obviously didn't work out.
