Well...
First of all getting a website is dead easy and dead cheap. On webspace you can get some for literally 1 euro per day (from
www.one.com for example... sorry for spaming, but just providing an example).
On the score, here's some general issues (I'm working on something right now so I can't give a precise feedback).
* There are many elements clashing. staccato dots with others, the name of the work (klaviersttuck) on top with legato lines, etc. It is a tedious job, but print it out and note each and everyone. Examples: p2, top of the page, the name of the work. the number "3" of the tuplet in bars 38 and 41 touch the legato line. Bar 42 the "3" is hidden behind the legato line. bar 68 the crescento lines towards the end are hidden behind the beams and the tuplet signs. etc...
* Some things need a bit of clearing up, not so much from the pianist point of view, but rather for a more academic approach. I'm talking about the use of layers. At a bar you use both 1 layer and 2 layers. I know it's frequently met in piano music (I'm also a pianist after all), but never the less some things need some clearing up. Example: bar 43-44. The E (mi) in the right hand changes layer over the next bar, which creates a little unbiguity.
* I know that you're German and studying in Germany, but perhaps, you could provide a translation to the terms that people who don't speak German, can't understand? " noch langsamer als zu Begin", "mehr beweg", etc. I can probably guess what it means... mehr=more and beweg=fast?slow? but it's rather risky.
* You have 1 single pedal point "mit pedal". Does this mean that the rest goes without pedal? With pedal adlib? other?
* In the first page, first bars, why do you use the 8vb sign on the low G, left hand, when in the next system you have a low F#, without an 8vb? Doesn't seem too low, or too important to use it really.
* bar 92: Disconnect the truplets (beam wise), or make the beam a 9plet instead. Right now they are confusing I think.
* Finally, find a way to add one more system on the last page, for it to reach the end! It's a shame such a beautiful work to leave "half" (not really, but anyhow) page empty. Or save a page and make it 10 pages instead of 11.
Hope these help. Most comments are rather objective, but some (the German language for example) is mostly personal... :-/
