Analyse my bluff v bluff spot

Richard~

this is my 320 dollar qualifier for prague. We're playing BvB vs a villain with a 75-80 aggression frequency or something. I like how I played this cause I feel I had control of the hand all the way, but there's one big thing I'm leaving myself open to and it's not a shove but rather something else from villain:
