Yes, Unfortunately the video camera makes FF sound like mf and pp sound like mf as well. I probably should post an audio example alone with better sound quality. I find that a video is much more interesting to listen to and watch than just audio so that's why I posted it. hmmmm, what is everyone elses opinion on this I wonder? (Video or just audio)
OK, I should start of by saying that your performance is respectable in that you got through it with a fair degree of musicality; so it's not a question of whether or not you can play the piano.
That said, achieving the drama suggested by daniloperusina is not only a question of dynamics, but also a question of phrasing, articulation, etc. I think you could think about these, along with the concept of gesture. I must say, however, that near the end, your playing seems to flow more naturally (maybe the nerves went away). It is only here that one finally gets a sense that the music is 'breathing', per se.
So, for example, try thinking of the opening motive in the right hand as a single gesture. I will post a video on Youtube to demonstrate what I mean. Please don't take it as me being a pompous ***, I sincerely want to help.
