A Few Animation Faux Pas
There's a small problem with the way you introduce the main character, May. The movie goes from showing the red-haired guy to showing May's feet. The viewer has no idea that a second person is about to be introduced, and the natural assupmtion is that the pair of feet belong to the one person we've already know is present.
You need to one of two things. Either show a full body shot of the red-head guy so that we can see his pants and shoes. That way when you cut to May the viewers know that it's a second person because the legs look different. The other thing would be to have May's feet walk into the alley. Since the viewer knows the red-head is already in the alley, they immediately understand that this is a second person being introduced.
