Hello, Eduardo_EVF, and welcome to TASVideos!
I'm here to conduct a review of this submission so here goes.
Review:
I got the movie to sync, but it should be noted that there's a lot of blank input after the last input needed for the ending sequence. Removing the blank input means the actual length of the input is around
11:43.38.
I watched the current RTA world record to compare against your TAS to check some things:

Something I noticed throughout was the RTA record was faster than your TAS in small places throughout the game. When comparing level by level, there's small optimizations seen in the RTA run that slowly gets ahead of the TAS, whether it be doing lag reduction or better slight movements to reduce waiting. The language differences only apply between stages as the number of textboxes in stages remain the same, so version differences aren't a big factor. Something I also noticed was that on the Mu boss the RTA record seemed to get more favorable boss actions resulting in a faster kill. Luck manipulating the Mu boss to use the rock dropping attack would definitely make that fight faster. If you could get that luck manipulation to work there, it's possible that the other fights could also be sped up with better luck.
It's a perfectly reasonable first submission at this game but it definitely needs a more fine tuned run. Take your time to first research strats if there are any available such as existing RTA runs out there. Try applying those strats in places your run seems slower in as well as try possibly faster strats if you catch something others didn't see. You have as much time as possible to make a TAS that's very refined and hard to beat.
tl;dr A number of small places where time could be saved compared to RTA runs add up across the run, making this submission suboptimal.
