Ruafo, at 1:48 you play an extra f# in the melody which is supposed to be held down only, that's what the tie means. In other words, in that bar, nr 6 from the end, you're only supposed to play f# once, then the e.
From 1:26 onwards, you take a lot of extra time on several beats, where the music should simply flow along.
Anyway, it sounds quite nice for music-making at one's own private pleasure.
But as to the ideas about a higher musical education, no. The pieces you list are nowhere near the kind of musical and pianistic ability you need to have.
Try this as an idea of what you'd have to be able to perform:
JS Bach: Preludes and Fugues nr 1-4 from Das Wohltemperierte Klavier, Book 1
WA Mozart: Sonata in C major K 330, complete
Lv Beethoven: Sonata in f minor, Op 2 nr 1, complete
Chopin: Etudes Op 10 nr 3 & nr 12 & Ballade nr 3
This is repertoire of a sort of average difficulty, not even close to being seriously demanding, but as long as any of this is too difficult for you, thinking about applying for a conservatoire is a waste of time.
So, consider other things for a professional career, or practice 12 hours per day the next four years and prove me utterly wrong! :-)
With kind regards!
