KK: right laydown on the turn?

[dot335]

Since this was only my fourth hand on that table I had no reads on MP1 and CO.

At that point I was very concerned about a flopped set or a x/7, that somehow decided to see one more card. Q/7 is also possible at nano limits like that.
But im still not sure if it was the right laydown.
I'm quite new to poker so I would be happy to hear your opinons.
