Yes, shame about the streamer, but the shot still conveys the emotion.
Perhaps you could crop slightly higher and to the left to remove the streamer & near window frame to focus more attention on the couple.

Her neck is a little thick looking due to straining anterior neck muscles to maintain the position.
Perhaps a little Liquify tool to shave off some of that thickness either from the front or the back.
Or you can try a little burning at the back of her neck.
