Though this scene is the shortest of them all, I still found it a challenge to complete. Drawing hands is one of the most difficult tasks for an artist, particularly getting the proportions right and making it suit the style of the animation.
My first try didn't go too well; this hand looks very out of proportion and I struggled to make it look right whilst animating.
My own hand as reference
However after trial and error, I finally managed to produce a piece of animation that works.
