I'm fairly new to PLO and was hoping to get some constructive feedback about spots such as the below where I'm not sure how to play.

This is my first post so go easy on me!

Seat 1: HERO ($172.80 in chips)
Seat 2: UTG ($114.41 in chips)
Seat 3: MP ($233.81 in chips)
Seat 4: CO ($118.68 in chips)
Seat 5: BTN ($232.89 in chips)
Seat 6: SB ($55.06 in chips)
SB: posts small blind $0.50
HERO: posts big blind $1

*** HOLE CARDS ***
Dealt to HERO (BB) [Ts Kh Qd Ks]
UTG: folds
MP: calls $1
CO: folds
BTN: raises $3.50 to $4.50
SB: folds
HERO (BB): calls $3.50
MP: calls $3.50

*** FLOP *** [2s 5d 6s] $14 pot

HERO (BB): checks
MP: checks
BTN: bets $10
HERO (BB): raises $25 to $35
MP: folds
BTN: raises $83.37 to $118.37

Pot: $167.37 ... $83.37 to call with another $49.93 behind and we're covered by the BTN.
Only have 40 hands on the villain, who is playing 15/10 with 100% CB

What does everyone make of the line taken here so far and how should we continue?
