The best way to get, which is very hard to get, a true feeling for Schumann is to listen to all of the recordings of her known students. I say hard to get because I had to ask a reference librarian to transfer his vinyl recordings of the "Pupils of Clara Schumann" to CD's. They are no longer available for sale, and no library will loan them out.
When you listen to Fanny Davies, Ilona Eibeschutz, and Adelina de Lara, you come away with a definite sense of a compositional signature to the man's work. That is in no way is present in the OP's rendering because he has never had any exposure to how the music was originally played.
A recording that you can obtain is Carl Friedberg's two CD set, "The Brahms/Schumann Tradition." He was a student of Clara Schumann and was personally coached by Brahms. The Schumann selections are the Kinderszenen, the Novelette, the Symphonic Etudes, and the Romance.
In all of these recordings you hear the original performance practices that I expound upon in my thesis, and most of all you hear a definite sense of melodic flow.www.marstonrecords.com
for those who want to hear a true piece history from a man who taught at Juilliard for 23 years. And, with the exception of the Schumann, the selections were all recorded live at Juilliard. (When he was in his 80's!!!)
Earl Wild recorded the Hammerklavier Sonata when he was 76, and Miecyslaw Horszowski played brilliantly at Carnegie Hall when he was 97. If I hear this old age BS one more time, I am going to lurch!
