waltz in f minor

https://youtu.be/Q6EBk0Pz6fs

my seventh composition, would more than love to hear feedback 

It would be helpful to see a score.  There's a certain charm to the piece, but also some harmonic awkwardness in places.  But for just your seventh composition, it's quite promising!

thank you for the reply, and here 😛

Simple motives are the best, and you've got a good one going.

If you're able and not sick of it, I'd really try to take this piece and develop it (not necessarily expand it), because there's a lot that could be done here, especially since you're so early in the learning process.

1. It's good that your main motive has rhythmic variation, but I'm not always so certain that it's intentional. For instance, the version we hear at the beginning sounds cleaner to me as the kind you have in mm. 35 and 39. The variation you have in the F minor section between straight eighths and the dotted figures is nice, though.
2. A couple jumps in technique that sound a little abrupt, talking about mm. 21 and 44. It's a pretty substantial change and it doesn't feel like it's supported well enough to me. A bigger lead in/out or a pattern change in the left hand could help with that.
3. The resolution at m. 56 jumps out to me as a little odd; it's plagal in A-flat major, but coming off of VI in the original key makes it feel a little sudden because you have two tonic-functioning chords in a row. Your bass counterpoint in that phrase is very smooth, so use that to your advantage and really sell that modulation melodically; I don't think you have to be so harmonic about it.
4. I'm not entirely sure what you want to do with the end section. The chromatic lines against the new tonic are pretty cool (I think some people call them line clichés, but I don't remember), but it's an entirely new key, so I'd take the extra time to really justify that big change. You've got a decent start to an idea, but it's not just repetition that makes things sound proper, but the time and space to make those things feel worth it. 
5. In that vein, I'd also let yourself develop the melody more. You have two distinct sections in two different keys (the waltz part at least) with a decently strong melodic idea; I can tell you know that it needs more variation because of the flourishes and stuff I mentioned in Point 2, but what if you made those variations two or four or eight or sixteen bars or a whole new section... you see where I'm going with this? There's a fine line between developing an idea and wasting the audience's time and I'd encourage you to try to explore what that line is.

Like I said, great ideas; I'm excited for this and you!
