Is this too aggressive? PP 2/4

[lightw1thoutheat]

This was my first orbit, and i didn't have a note on the bb. Up to this point i hadn't seen him play a hand, which made me think that he was at least reasonably tight.
I'm wondering about the turn aggression, is this standard, or did i go way overboard? i was very confused as what to put him on. also, should i have bet out the flop? comments all the way please.
