Nocturne impov. looking for comments

I am interested to hear any feedback on one of my piano solo improvisations inspired by Nocturnes:

Despite your use of the line cliché it still sounds quite fresh.  Your voicings are crisp.  It's just a shame that it's so short.  I guess if you overstayed your welcome with these standard progression it might start to sound too repetitive after a while.  But it has quite a nostalgic feel and it reminds me of some of my favorite VGM tracks that I know and love.  It's definitely got heart.  Thanks for sharing!

I agree with @PeterthePapercomPoser on all his remarks. If I could add one little thing, I think the music could benefit from a bit more space in the melodic line. There are a lot of moments in which you have at least one note on each beat non-stop. This is not wrong, but diversity is always good and can make for a more effective line. Good job nonetheless.
