I think the models of the children were very functional especially because they kept their distance to the sleigh, so you really made the most of your improving Blender skills! I loved the more metal version of Jingle Bells, and your voice over was really nice quality!
Noticed some small bugs like children glitching through the ground and the sleigh not always aiming in the direction it's moving, but it was good fun and not too hard, I was able to complete it in a comfortable cozy manner.
