Mr. Stephan,
I reviewed your score. I agree with Chris, the calligraphy is excellent! I wish I had a piano accessible to try your piece out. I am glad the tempo marking is adagio. I think, if I was to learn and play your piece at presto speed, my fingers would need to be hospitalized

One thing I'm confused about: if this is a piano piece there should be braces around the grand staves, no?
I wish I could hear it, even, perhaps in midi format if not on a beautiful grand by a famous concert pianist.
Look forward to some realization of the written score,
Riley
