About your blocking:
The main thing that sticks out are the poses on x112+ and around x220. He looks like he's talking to those flat shapes. If he's that much in love, I would have him gaze to the horizon or the sky, like he's on cloud 9.
Also have him look more straight ahead with left/right direction changes inbetween (roughly). Right now he's a bit fixated on the screen left part.
