Villian is fairly loose and loves to chase straights and flushes. How is my line here?

Poker Room skin
No Limit Holdem Ring game
Blinds: $0.05/$0.10
5 players
Converter

Stack sizes:
UTG: $10.25
zepth: $29.45
Button: $11.40
SB: $9.80
BB: $7.45

Pre-flop: (5 players) zepth is CO with
UTG calls, zepth raises to $0.5, 2 folds, BB calls, UTG calls.

Flop: ($1.55, 3 players)
BB checks, UTG bets $0.5, zepth raises to $2, BB folds, UTG calls.

Should the 3bet have been bigger here?

Turn: ($5.55, 2 players)
UTG checks, zepth checks.

Knowing the villian I thought a check here was the safest option, there was a very good chance he was chasing the flush and just hit it. Is this check justified?

River: ($5.55, 2 players)
UTG bets $3.5, zepth ???

Easy fold right? Straights and flushes completed should I just lay this away and wait for my next chance?

if you fold river this is fine, but if villain is donkish enough to pay off with Ax, i'd bet the turn for 3.50 (folding to a raise) and then check back the river

Flop raise is fine.
I'd fold river. It's not just the spade to worry about the board got incredibly bad with AT/A9 and random mid pair/gutshots also outdrawing us too.

Yeah this is pretty standard I think.

I'd need some serious read before I bet the turn.

With this villain it's not so bad, but I'd typically be firing at that turn.

Yes.
