All the timing is completely off I just spaced out the timeline so that I could read it easily in photoshop. I think each frame holds for roughly a second, with the exception of a couple of keyframes where I just needed to get the animation going so that it still read appropriately. Best example of this is the 'wait a sec' finger pose where it's three frames to really accentuate that action.
I added some actions to demonstrate a few animation principles that I wanted to get in there. The lifting of the boxes before the boy reaches into his pocket gives me the opportunity to show some shifting of weight and get some nice secondary motions happening with the balancing of the boxes.
Also found a nice expressive moment when the girl notices the dog, is tempted but then ultimately turns away. Really tried to make sure that she goes through all of it distinctly, surprise then temptation/ intrigue then a resolved refusal. These are all quite small and subtle poses but I feel like that if I hit those keyframes strongly enough it should come across well.
