This just looks so weird and cool... I can't even... Haha! It's hard to find stuff wrong in here, I like all of it. Especially her expressions, and the seedling is so cute! Keep it up!
I really like your main character and her expressions and your seedling is very cute. The story is very clear and I never found myself being confused while looking through it. This does seem like a long story though and it looks like you will have a lot of still and slow panning shots in the final animation, so I'm just warning you that you have given yourself a big project. If you think you can do it, then go for it.
I know I've talked with you in person about the storyboards, but I should probably leave a comment here as well! Your story reads so well, I was never asking "what is happening in this scene?" while skimming through it. The expressions you've chosen for your characters are perfect and make the story that much funnier. Looking at it now I agree with Wendy that the neighbor scene isn't exactly necessary, and the way the ending scene could be executed could be smoother, but I still really enjoy all of it. At the end, I would love if you showed a long shot of them flying through the skies or of them reaching her destination, since I feel like it would be a nicer conclusion to all the other great things you have going on in your storyboards. Great job Kristine!
