found a new way to design keyboard and guitar music with photoshop stamp feature

Hi,

This is not really the place to advertise for collaborative work. Behance might be a better place.

As a side note, notating music on an image editor sounds like flogging yourself with a wet fish :-). There are notation applications such as Sibelius, Finale or Dorico that are designed for notation and include both classical guitar finger positions and chord chart style graphics.
