Tchaikovsky piece for 14 year old?

I’m 13 years old and I’ve been playing piano since I was 6 (8 years). I’ve had one or two bad years but I’m still fairly good. Just for a better indicator of my level I have played Beethoven’s Sonatina in G and the Spinning Song by Ellmenreich. I’m looking for more of a challenge and I thought perhaps I’d like to play Tchaikovsky’s opus 39 numbers 6-8 The new doll, The sick doll and The doll’s burial. I was just wondering if anyone thinks I can do it?

If you practice, I think you can do it.

Beethoven Pathetique Piano Sonata No. 8, Opus 13 in C minor, Part III, Allegro by Tzvi Erez
