Good luck with your final animation project Mat, I'm in the scripting stage of mine as well
What process are you going for? I'm looking at finishing the scripting and moving onto storyboarding first and then getting basic timing in by sketching key frames out in Plastic Animation Paper (an animation tool, the basic one is free https://www.plasticanimationpaper.dk/). Then it'll be the long slog to get it all together for January
I've just been going through your tutorials and they are all quite good in showing different ways to do things. The dynamic joint chain is nice (is that one your voice?), the only thing I got stumped with was that its real easy to accidentally attach the IK spline handle to the original curve and not the hair. I think if you get the chance then it'd be nice to mention that as it might stump some people.
The balloon is looking good but the return from the swing looks a little strange, maybe a little tight or something as if the balloon would have a shorter string or something. Unless you've already done it I'd suggest getting a balloon and film yourself making similar movements. If you could film it from 3 angles and move it forward, back and side to side then it'd be good reference vid for the future
