You won't know unless you practice on an acoustic piano....
The thing about Yamaha CLP is that disregarding how you are hitting the key, it makes the wonderful recorded grand piano sounds. Yes, it has hammer action response and it feels as if it's a real piano. But you'd probably notice, when you try to play the piece you know on an acoustic piano, somehow, it feels a lot more difficult to control your sound quality.
If you have a potential or not depends on if you can control your touch, create multiple colors, manage your dynamic ranges, etc, which you can only know by playing on an acoustic piano.
You are playing wonderful pieces like Chopin Waltz and Fantasie Improptu, of course, you have a potential. Now I have many nephews and nieces and encountered many kids, if you don't have a potential, you won't try to play those things.
