Nice work!
You did an amazing job for this! I just wish you had more added to it, but it is perfectly fine as is.
The quality warning was a good idea since it is very graphically intense. My computer handled high quality the whole way without a problem, but I have a high-end computer as well. And the quality doesn't actually ruin the movie if you do set it low, so it is a very effective measure to avoid slowdowns and distortions.
Very nice work! Keep it up!
