These variations are very musically effective, and I enjoyed them thoroughly. I especially enjoyed the rhythmic and stylistic variety, which kept my interest throughout. I also really appreciated the nod to other great composers whether intentional or not (ie. the Brahms-like third variation, the Shostakovich waltz-like variation 6, the very clever Cereli Theme/Schubert Serenade mix in Variation 9, the Liszt/Thalberg like coda towards the end of the last variation).As far as your playing goes, I have a high tolerance for mistakes (sometimes I prefer them), low tolerance for poor musicality. I think your playing is very effective, and in my opinion, the mistakes and perceived technical deficiencies in your playing do not detract at all from the musicality of the piece.Altogether I think this deserves more attention, and I'd very much be interested in hearing more of your compositions.
