I would say it's very hard to WOW in the piano world, especially when it's on a digital piano. I find it hard to make any any real comment on playing ability with the use of a digital piano.
The dynamics of an acoustic piano, blows away even the most expensive digital piano.
I would enjoy hearing you play an acoustic piano.

I know it's not always easy to get access to a decent acoustic piano but it's defiantly worth the effort.
