Hmmmm,
Well the tempo, Allegro Ma non troppo (fast but not much).
Once all the deatails have been covered such as - Notes, Dynamices, expression marks, Rhythm, pedaling, rubato and stylistics detail, then the performer can be free with the tempo, so I'd advice not to worry about speed yet, just the more important part, the 'detail'.
I recorded this over 5 years ago, since then I've changed a lot of things through really looking closely at the written text.
It's a little like sculpting, chip away and you'll creat a work of art.
