Flawed Play that was still winning?

[Xylem]

OK there are millions of errors that ive made in this hand including : preflop calls, and stack sizes, but i know this.
What i want to know is what villain looks like he has and what line you would take after the flop.

Btw villain seems a lil lag and ive seen him bluff me with crai before.

Results to come.
