Great work, you should be proud!
It is visually interesting leaving the harp in. I probably would not have, it's heavy and takes up a lot of space.
The pedal functions are a nice touch.
I have half-heartily considered such a project. Free pianos are everywhere. I recently got an antique pump organ that I will attempt to turn into a desk. With secret compartments. Maybe a bar? Thanks for stimulating my creativity.
