Congratulations, an arrangement very well done!
In my opinion, mostly of your arrangement is better than the Liszt's solo version.
When I play this piece solo I use the Liszt version, but I add some "missing" information, specially in the Coda. So it is an "almost arrangement".

By the way, I recorded a full Liszt CD which hopefully will be published in some months (Sonata in b minor, Après une lecture de Dante, Totentanz solo and Les Jeux d'eau a la Villa d'Este)
Nice to see you recorded some Tausig too, I will check your website carefully again later today
I'm working in the recording of complete Tausig's music, first CD is already available:

All the best
