Honestly, I wasn't that impressed by this. It looks like there are some people who like it a lot. That's fine for them, I suppose. I don't even think the final product is that good looking. It was also too short. I know time lapses by their very nature aren't supposed to be long, but it could have been better.
It's nice that you appreciate your own work. This was just not enough for a submission. The music wasn't bad. This wasn't that special. The colors could have more shading, too.
