Too aggressive?

[CashFlo]

Live 2/4 game. I had been there for 15 minutes, and noticed that the table (and villain [UTG] ) was EXTREMELY loose. No reads on their aggression/passiveness. I had no image because: 1. i dont think these players even bothered to make a read. 2. i had been there for 15 minutes.

Sooo...too aggressive? I was hoping the guy was playing his overcards or his lower pocket pair aggressively.

I'm not sure, but I think my river bet isnt so good.
