I don't like when pianists complain about tempi, and I actually like this tempo and can see that it can be very beautiful.
Though, the danger with this tempo is that it will become heavy, and, frankly, it becomes a bit on the slow side (not tempo wise, but "walking in quick-sand"-wise).
Another thing with slow tempo, is that the stacatto can't be as short as you sometimes make them. They sound cut, and that's not a very good thing.
On the more detailed aspect:
Check the rhythm in the beginning. After listening, I still don't know who I would write what you play. Try to play it without the short note.
Many pianists forget to phrase the chromatic repeated notes, and this gets even more important in your tempo.
Also, be very careful with voicing the lh. The top voice of the chords should be dominant, together with the bass.
