Feedback for ostinato piece

Hello Everybody!

I'm kind of new here,
and I would like to have some feedback on my first ostinato based solo piano piece:
 

Thank you for your help,
Everybody have a nice day!

I enjoyed this piece. W¡But why do you call it ostinato piece? Yes, there is  pattern of repeating one note, that changes. Is it that?

Thank you! Well, I don't know what's the correct term for pieces that uses ostinato rhythm only (not repeating pitches, just repeating rhythm throughout the whole song)?

Wow.  You are obviously quite a talented pianist and composer to have written and played this yourself.  I admire your harmonic language and dexterity.  One is never quite sure where they'll end up listening to the harmonic progression in this piece and yet it repeats seamlessly and ends in a quite a novel and unexpected place.  So I guess that since this piece starts and ends on the tone F .. that means that it's in F major, right?  Just kidding ... LoL  Nice Job!

I liked this! Very nimble and light, and it fits the title perfectly 😁 It's fun as a standalone piece, but I think it would be nice in a suite for piano with some contrasting movements. It leaves the listener wanting more, which is great. Well done
