$5-45 on FTP. A few hands

[PoliticalRefugee]

Ok I started playing these after being crap at everything else I played and surprise surprise I started losing so now am trying to find where I'm going wrong so I'd like some advice on some hands.

1. Does this look OK? I really hate calling raises preflop early as it always feels like spew and the raise here can be anything. So from position I generally 3-bet TT+ and AQs+ and maybe others if I've seen villain raise stupidly before.
This is FIRST hand by the way
