Great and fantastic achievement! You should not be so surprised there's not much Sorabji posted hear, as his music is such a money and time investment. I don't own a single score.
It is a pity the recording didn't get the dynamic contrasts.
It's certainly a time investment but not perhaps quite the financial one that you appear to imply; as of June last year, we have been issuing all of Sorabji's music and published literary writings as .pdf files as well as hard copies on paper and the principal reason for taking the decision to do this was cost for the purchaser - for example, it costs us more than £50 (c.$75) merely to mail a copy of the typeset edition of 100 Transcendental Studies to anywhere outside Europe. To give an example, we supply Opus Clavicembalisticum to anywhere within UK for £60 (and rather more to supply it elsewhere) whereas, in .pdf format, we charge £15; to give another, almost all Sorabji scores of less than 50 pages in total are supplied as .pdf files for £5 each.

Congratulations indeed to John on his traversal of one of the most immediately attractive pieces from Sorabji's early years; keep up the good work! Yes, better audio quality would be a blessing and a better piano likewise, but be not discouraged! - and perhaps at some point you might care to have a look at the work's later (1933) "big brother", the Fantasia Ispanica, a multi-movement work of around an hour's duration but still shot through with the kinds of attractive and appealing Hispanicism that abound in Fantaisie Espagnole (there's a typeset score and a splendid recording of this by Jonathan Powell).
Fantaisie Espagnole is dedicated to one of Sorabji's most longstanding friends, Norman Peterkin (1886-1982); when, in 1946, Sorabji dedicated his
Concerto per suonare da me solo to him, he did so, as he put it, to "take away the taste of that insipid baby-piece" (by which he meant Fantaisie Espagnole. Fantaisie Espagnole is not, however, to be underestimated and, on one of my regular visits to the composer in the latter 1970s, I could hear him practising it with not inconsiderable verve as I arrived; once in the house, he said "do you know, it's almost 60 years old now but it's really not bad!"...
One other discouraging factor used to be that most of Sorabji's scores were available only in the form of copies of the autograph ms. (and some of these are far from legible), but this is no longer the case; a fair number of them have now been edited and are presented either in neat handwritten format or (as is the case with the all the more recent editions) in typeset form (sample pages from all of his scores can be seen on the website).
Anyway, it's good to hear of your findings, John; anything that might encourage people to practise Sorabji and derive palpable benefit from it can only be a good thing!
Best,
Alistair
