Thanks, furtwaengler and birba, very flattering. Yes, there are a few minor 10ths to reach. Interesting about his later works being "obscure", I didn't see that, but it gives a perspective to the whole set that I like!:)
Nikolasideris, you don't have to like my interpretation, of course, but I didn't hold anything back. I wanted a great deal of rythmic and dynamic 'precision', and a carefully shaped sound, to make it 'speak', for me, alas. So there's concentration, but I wouldn't say 'numb' or 'nervous'. 'Banging' on the ff's, or rushing an "Allegretto" tempo was out of the question for me, but maybe that's not what you meant. Anyway, thanks for sharing your opinion!
