A piece for piano I composed

I would like to hear from you an opinion on this piece as this is my first time I was writing a piece just for one instrument (in this case piano). This is also the longest piece I have written.

I need to make kind of "tips for the beginner composer",

but I want to use the time I have left to try and finish my piece.

Anyway the tips I keep giving is- longer isn't necessarily better. 

I didn't have anything I could stick to.

No repeating theme I noticed.

Sometimes it's fine, I tend to do that too.

You didn't change the dynamics, and that bothered me.

You can't keep playing loud all the time.

Loud all the time is not loud.

That leads us to the other tip, your good choice:

you wrote for one instrument.

You limited yourself.

And that's so great- that's the other tip I usually give to amateur composers

(not to worry, I am one myself but I have a few years of experience).

When you have one instrument you have to use your other tools.

Modulation, dynamics, tempo, rhythm etc.

Challenge: try and limit yourself even more. 

Write a piece for piano only using F E and Bb.

Or any other combination.

Try to have a repeated theme.

Remember that longer doesn't mean better.

I hope I wasn't too hard on you,

now I got to go wash the dishes or my father would kill me.

Hope that was helpful,

bye

The main issue I see here is that the writing, without being bad, is not very idiomatic for the piano. Sometimes there is a sort of dialogue between one phrase in one hand and the other, but most of the time the development is vertical with both hands in parallel motion. This is not bad, whenever there is something more that takes advantage of the possibilities of the instrument: polyphony. The way it is, it seems like a long prelude or introduction to something (too long for that). There is also a come and go in styles: baroque, romantic, modern.

You were not too hard on me, I understand your feedback and also Luis's feedback. As I listened to the piece again I started to notice the things you said should be improved. I remembered how I did not put much time and dedication in this piece because I worked five minutes one day, five minutes the other without really listening to the previous things I've written so every time I introduced new themes without making a clear connection. I will try to improve the next pieces I write as I have learned a lesson from this piece - you must be fully focused and dedicated to the thing you are composing in order for it to be good.

I am not trying to create an excuse for why this piece is worse than others of mine, what I am trying to say is that there is no need to apologize because of feedback harshness and that I appreciate every feedback I get because I try to learn a new lesson from each one and thus improve and make my new compositions even better.
