hey man, great start and I love the character designs! pls pass on my high five to Claire 
looking fwd to the full animatic!
The calendar shot feels a bit short, maybe add a few frames more to read in the information.
I’m wondering if there’s a way to tighten up the pace slighty so you can get quicker into the story of him building his rocket…
What if you start with the an establishing shot of the house, and a school bus rolls in, he runs quickly into his room to get started. The calendar could be in his room by the door, and you can frame on that close up as he runs by. He doesn’t need to stop as I think it’s quite clear already that’s he’s eager for that calendar date from the framing of the shot.
anyway just some ideas… he’s kinda hard to explain in words… hope it’s makes sense.
shot numbers would be cool to make it easier to crit ;p
