Score feedback request

[Aura]

Hello

This question may be semi-off-topic. If you feel it is, let me know.

I'm a blind music student learning to typeset my compositions with Lilypond.

I would like to ask feedback from the community about one of my works (it is a
Lied). I ask from Lilypond list for three reasons:
* I can't (obviously) review the visual appearance of my score by myself.
* If/when there are visual glitches in my score, people here can probably tell
me how to fix them.
* There are lots of professional musicians on this list whose opinions I value.

My score and the rendered PDF file can be found at
http://sange.fi/~aura/Lied/.

The score is written with Finnish note names (they are the same as in Germany,
so what in English-speaking countries is b, is h in my score). The source code
also has comments written in Finnish, but they contain no valuable
information.

I'm especially worried about the way I have marked dynamics, because I don't
know about the tradition regarding their positioning (should they be placed
between the two piano staves or should they be marked separately for both 
hands).

My pianism is horrible, if you look at the score and spot something that is
impossible or very difficult to play, you can tell my about it too.

Thank you for your time.
