Specific Change the expression of one of the characters!

Sooo I shot a poster for a movie I'm working on and while the vibe is perfect I don't like the expression of one of the guy in blue.
I just wish he was smiling a warm smile or maybe laughing along with the girl.
Any edit would greatly be appreciated and I'll give you a 'poster by' credit if you want!

Quick hit with neural filters and slight burning in of glare on girl...
