@Alex Jordan Thanks for your compliments! The old one is still up, though I guess no longer on the site.
@Jason Self I appreciate that! The first video definitely had huge audio problems, which I did my best to cover up, but which are noticable still. The second had a few points where my voice was "swallowed" by the music as well. There are other things... the timing on the eye animation in the second video could be a lot better. But I'm still an amateur, and there's limited time. The things I asked for feedback on, got useful feedback on, then never had the chance to change are the most embarrassing points for me, because I know others could identify them. But I still think that all considered, things went well, I'm still more proud of it than I am sensitive to the flaws.
And watching the first and the second side by side, it's obvious that the second was a big improvement and that I had learned a lot!
