Hi failed,
I just listened to it--very nice! It's hard to tell whether you might use more shifts in dynamics, or the tape was evening out your dynamics. I thought it should be more pp at the beginning of the 3rd page where that sequence begins that builds to the climax. Maybe make that climax (bottom of 3rd page) a little more drawn out. At the very end, make that rising RH passage just vanish into thin air.
Also, I think you could loosen up the whole thing--your tempos in the main opening theme are a bit too strict in the LH melody. Rachmaninoff wrote these luscious, sexy melodies that really need their long gorgeous lines to be brought out to the hilt! The RH part is like shimmering water, so you never need to have that figuration too "clear" or prominent such that it overshadows the melody. Don't hold back! I thought you did great on that difficult passage on the mid-2nd page.
Have fun!
