AKo agression question

[OddWorld]

It somewhat feels like I played this right, but I don't know if this level of agression is good long term. I know that UTG+1 is fairly loose (LAP), and all I knew was that the BB was very loose (22 hands; VPIP=50%). I honestly figured, at the time, they both could have had anything. My gut told at least one of them had a low pair, or at least one of them had a spade draw. Their hands are at the end of this post.

This is the right amount of aggression. Nice hand.
