Looking for some more Feedback!

As Ben said, repeats are fine, but if it's your choice not to change harmony, I would at least break in the pattern a bit more. Add passing tones and grace notes here and there, and these half-notes in the left hand seem to leave plenty of space unused. You could break them into quarters doing the exact same harmony or use the second quarter to spice things up.

I get a bit lost in the part from bar 9 onward. Maybe because the pattern is weird in the next 4 + 4 bars. Also these long empty half-note spaces aren't helping, so if you were to follow my advice from above, these would get even more playful here. That's really the first thing I noticed as it feels like your piece is dragging then speeding up - more than once you have half of the bar just playing these half notes, and then the other half of the bar is absolutely stacked. If that's the deal, I'd work on creating a more predictive patterns.
