Very high degree of Spanish influences, shifting rhythmic syncopation and time signatures and Phrygian mode. You clearly know what you're doing. This is a very pianistic piece, despite never having written for piano before. All of the chords and embellishments fall easily under the hand, and you're careful to give time for the performer to breathe. I'm still quite an amateur in terms of compositional technique, but I would say as a pianist this is a very fine start to writing for piano. I would recommend exploring the instrument's capabilities a little bit more in order to balance out the edge. You could, for example, have added some of the lower bass notes in the left hand accompaniment for bars 23 - 24. Since they're so low and resonate for a significantly longer time, they give a much richer, ringing tone quality to your staccatos. Not to mention, it helps to activate the resonators in the piano, leading to a much richer tone in general, and it lends to a much more powerful and dramatic effect. However, this is still a very well thought out composition.
