You're getting there! I think the first two pages were fine. I still like your style regarding the left hand.
Measure 30 - You could hold the hold a bit longer. Same goes for the one 16 measures from end.
Measures 33-34 - Too fast with this run.
Measure 35, 37, and 45 - Coming in too early with left hand. If you count 1-2-3-4, the left hand has to wait until second count.
Last line - Since the rhythm is very straight forward, you have to make sure to count out all the rests. Anyone not looking at the score will not notice if you don't but those who do will.
Did you really mean "saloon" music? or "salon" music. Maybe this is how you say it over there, but here when I think of saloon music, I think of a bunch of cowboys sitting around in a saloon playing poker and drinking whiskey. I didn't know cowboys listened to Chopin music too.
I wonder how it sounds on a 'honky-tonk piano.
Hehe! Ah, not really saloon music. Cowboys and Chopin...will, that is an odd match
Bar 30, it feels not natural for me to hold it down longer. If I do that, I must drop the tempo in the bar before.
Bar 33-34. Yeah well, fits so natural for the hand so I cannot hold it back really. I will try better next time.
35, 37, 45. Just that it feels so slow. Perhaps I chose a too slow tempo for the B-part but I should correct this.
At the end. Well, I do not count and am not sure if it is important either. When one compose an end like that, one must make it fit and I take a very liberal approach when I enter endings like this. Do it entirely on feel.
I take an example here. Listen to Rachmaninov when he plays his op.3 prelude. In the beginning, he does not count and it does not fit the tempo at all. He is not even close as he take twice the tempo when he should (according to the score) rest on the C#. He does the same thing in the end. He had to make it fit into equal lengths of bars. But well, one can probably not compare Rach with Chopin but we also know that Chopin was a very liberal rubato pianist. That is noted many times from his listeners. But there exist many contradictional fact as his pupil reported him to teach that the left hand is the the clock, while right hand plays the rubato. So left hand should be tempo steady while a more liberal approach can be applied to right hand. Not sure how this monologue fits with the end of the impromptu but I have a feeling that he left such an ending very much to the pianist to make his own. And so I do.
