Waltz No.1 in A Minor for Piano

Hello everyone!

I composed a waltz for piano during the weekend. I wanted it to be "easy" to play so I composed it with an accompaniment that does not need jumps or the use of the pedal.
It is still hard to play for me, so, while I practice, I leave it here with my initial live performance until I can play it better (it would sound awful with midi). 
My main concerns is always with the form, as I am not sure how do transition best between sections, when to repeat things or let them go, etc. So any feedback about that is more than welcome. 

The piece is in the form ABCBA. 
A is the main theme in A minor, which is repeated at the end. It is a frantic and agitated theme (and needs to be played rubato).  
B is a modulatory section and needs to be played without rubato and with the melody "singing". It is based on a long chromatic descending bass line so it is highly chromatic and there might be many compositional mistakes in this section. While it is the easiest section, I have troubles played it beautifully. You can listen to the only time I played it as well as I wanted in 2:01 from the audio.
C is a simple lyrical theme in A major.

The audio is really bad, it is based on different recordings so the quality of the sound changes a little.
When I practice everything and have a finalized score and audio rendition I will update it!

Hope you like it and any feedback is more than welcome! Thank you!

Hi there.

Let's go to the point right away.

Firstly, Nice waltz! I really enjoyed listening. There seems to be a problem too, by the start. It is definitely not Presto. The Bpm is more like 112 (I use a metronome). Presto is kind of like 180 Bpm. If you want a Presto, I would recommend writing something like the following: Presto (c. 112).

Secondly, I could definetely hear Chopin here! The ideas at bar 18 and 38 is also very good.

Thirdly, cantabile part seems nice. The immediate transition to G Major and back to A minor is extremely nice. Although in a Major Key beginning, it still keeps a melancholic atmosphere. The bars 49-56 area's texture is favorable. Bar 62 is played wrong. You forgot to play the (appogiatura) B natural.

Fourthly, From Vivace, there is a Key signature change, which I like. Again the tempo is played wrong. Bar 93 does not make sense

Lastly, from maestoso, I really like the texture. Bar 116 is one of my favourite bars in this composition! Then, it is go to the start up to the Coda mark. The coda is not long enough, though. Could be longer.

In conclusion, You have great composition ideas, but you still need more practice. Overall, I would rate this piece of music a 8.5 out of 10. 

Have a nice day!
