Well, Dallas...
I liked the introduction because you took advantage of the piano's rich qualities.
Issues/comments/praise:
I really liked the first few measures and the set up of the theme. Your harmonic progressions seemed to be focused on because of the lack of rythmic variety in the section between the intro and :56. It was great until :56... and then I was confused (about the style). At 1:37, the theme started to sink in. I heard your minor variation... though it was short and mainly in unison. After this... I am slightly confused (1:57)... but you do expand upon this later. I'm not sure if this is a variation of the theme (2:02), mabye you were mirror-imaging your theme (I'm not sure what the terminology is). At this section, the bass hand is not in continuous motion, which prevents this section from getting the energy and life that I think you wanted it to. At 2:26, the chromatic changes in the bass lend the section a feeling of urgency of motion, which is uncharacteristic of the surrounding sections (this might have been intentional). Use of low bass chords in sections like 2:55 can give the sound a gruff and indistinguishable texture, and you might have wanted this, but it sounds very heavy here. I hear an appogiatura at 3:03, which is great. And some beethoven-ish chromatic play at the end. Yes, a very sontata-ish ending. Okay, much of your piece is scales, which is a very classical thing to do. Your exposition and recapitulation were great. The beginning of the development was good, but I was initially lost in the second part of the development. Upon further listening, I was able to make sense of it.
I would love to hear more out of your sonata when it is completed. Good job at sticking to sonata-allegro form. I was a little bit turned-off by the usage of similar chord progressions through the entire song, but that is very minor. Good effort!
