This is a wonderfully played "Casta diva" arranged for left hand alone. You've played it so artistically that just listening to it without the benefit of knowing otherwise, I would have assumed that it was being played with both hands. Congratulations on this fine achievement!
I must admit that if I end up recording it in a studio setting, rather than as a live performance, I will be sorely tempted to use both hands! I'm not sure about the ethics of that.
Apart from having been at the performance (!), the thing that tells me it's just one hand is the time delay in some of the big leaps from bass to treble, where it's effectively a bass appoggiatura (as opposed to those where the bass and treble lie on differing beats). Ideally the notes should be a little closer together, but I can't jump much faster without taking risks.

I found an Internet site listing a number of RH alone pieces, but only one is available on IMSLP (it is the Alkan's study), which looks terribly difficult !
I would certainly agree with that: oddly, I think his lh only etude is significantly easier (obviously still tricky though).
