Hi CatlyNat and welcome to TASvideos.
For a first TAS, this wasn't bad at all. Unfortunately, this movie isn't up to the site's publication standards.
It's very slow and unoptimal in a lot of places, whereas the movies that are submitted here should be as close to perfect as possible. You slow down in a lot of places unnecessarily and use pretty slow level routes. For example, in the Donut Plains ghost house, you can reach the exit a lot quicker by bouncing on one of the Boos. In Valley of Bowser 2, you can clip through the yellow floor moving up and down to clear the section much faster.
Instead, you may want to upload it to
userfiles and post it to the
forum thread to get feedback.
If you want to improve this movie, look at some of the
other Super Mario World TASes on the site and carefully examine which tricks and strategies they use to complete the levels as quickly as they do.
If you don't already know how to use it, you may want to learn how to use frame advance to get optimal input. You also want to use Ram Watch to make sure you're always at the highest speed you can be.
We also have a
Game Resources page where many Super Mario World tricks are explained. It explains things such as 49 hopping, which is the fastest way to move without a cape. It also has several useful RAM addresses to watch.
I hope this helps you improve this movie. Good luck with future attempts.
