First Royal Flush, more aggression on flop?

This happened around my 100th hand of Ring NL, maybe 2-3k hands overall.

----
I didn't play agressively until the river because I worried about straight draws (AK, then Kx) but couldn't conceive of a proper reason to ditch top/bottom pair, nor the potential flush after the turn.

Thoughts? Even *gasp* fold this preflop?
