The overall story is in place, but I would encourage to put more emphasis on the pets and their relationships between each other. I think cutting to tighter shots will allow the audience to get closer and allow the character to act out a little more their affections for each other. This will allow us to empathize more with the situation.
I would also put more energy into the poses of the dog to get him more active in the scenes. I would invite you to revisit the earlier acts and see what you can do to make the dog, cat and woman a little more active in what they are experiencing and feeling.
Having the dog up and attentive helps showcase his protective and paternalistic behavior. Plus a little lick on the chick adds a nice comedic touch.
I thought it would be great to have the cat protect the chick from getting hit by the door opening and delivering it to the woman.
In the parting shot, I think a stronger more emotional shot would to be closer and allow the dog to say his good bye first as he was her first find. then the cat comes in and finally in a little lighter moment the rooster flies in on top of her head and we zoom out a little bit to show that they are one unit.
Here I wanted to show how sad the pets were and did not have much of an appetite. Then we should see the letter and the message..then the pets really perk up and we can even have fun with imagery with hearts fluttering or something visual to play up the decorative style. Then a cross dissolve or transition to show them sleeping happily. Remember to play with the relationships in a strong visual way.
