I tone down the movement of the guy, and I add this hand little movement for the girl to show she is very excited. At the end I make her raise her both arm as Neth suggested.
What I am now figuring is that should I remain the action of the girl pressing the guy's cap with her right hand and cause him loses his vision? Which is the reason why he struggle at the beginning and both of them started to lose balance?
Or should I take this part out (her hand press on his cap), and show that he is struggling because of her big movement and then they off balance? Or I should just remain both? Any suggestions?
Thanks and looking forward for everyone's reply! :) Have a nice weekend though~
