You are a traditionally trained artist why do you favor digital techniques...?
I found through my experience that working digitally affords my client and I a large degree a flexibility and control over the final images. Yes, a physical artifact is not left behind after the project is completed, but I am a commercial artist...
My concern lies with the final image created after that a project can become unwieldy as a physical object that needs to be stored, especially as completed work begins to stack up.
