Piano or just P.U?

[exotic fox]

This is supposed to a mech based off a piano. The only problem is that I don't think I added enough piano features, but don't what to do

Any suggestions?

I would add more features to envoke the type of piank youre going for (e.g. grand piano, keyboard, synth piano, etc) each type of piano has its own energy and color and genre
