If you have been playing only two years. then the question is, "For how many years have you been studying/training
prior to 'playing'?" Either you're not being quite honest or you have prodigious ability. Given the venue where you were performing (a recital hall somehwere with a fine Steinway) I suspect it was at an academic center where you are enrolled. If you're a piano major, you're doing a fine job so far, but no one would accept you without having had considerable preparation prior to your matriculation. Something doesn't fit with what you're saying.
Would you care to clarify for us?
