Feedback on Piano Piece

I recently have been working on a piano piece, can I get some feedback on the piece?

I would mainly get feedback on these but other advice is appreciated:

Form - is it noticible the ABA + coda form?

mm189 - is it clearly notated what to do?

is the rhythm diverse enough?

Thank you!

A surprising work.
The pace is a bit frenetic, although it calms down and contrasts a bit at the end.
I think the ostinato rhythm of dotted eighth notes predominates for the most part, but I do find that there is a lot of variety.
At measure 189 it is clear that this is a tonal cluster. I've never seen it noted this way before but I don't see a problem with it.

The piece runs very smoothly and the transitions are great.

I'm not used to this style but I stylistically I can't find any glaring flaws here.

On a practical level,
1. Are you sure this piece is playable, and at this tempo? I'm not that skilled so you'll have to judge it for yourself, but those semiquavers thirds can easily tense up my finger muscles, and the repeated octaves..., and repeated thumb notes? like bar 178, and Mr. big hands like bar 169
2. voicing issues like bar 13, the crotchets don't mean anything if the next quaver you are just going to bang fortissimo anyway

Hi @Ho Sen Ken!

Wow!  What a great and intense Bartok-like piano banger!  It reminds me of one of Bartok's early works Scherzo in E minor for Piano.  Although admittedly, your work is a bit more similar to later more harmonically adventurous works.  I'm looking forward to hearing more of your contributions to the forum (and besides sharing your music you could also tell us what you think of other composers' works!)  Thanks for sharing!
