Ooh, I've never thought of doing that before! Thanks so much for the suggestion!
That would be really great for practicing; having that bit of a reference and being able
to go over it and redo it without ruining the original, or redrawing the whole scene.
I will definitely try that with this picture, and will keep it in mind for other pieces as well!
Sorry it's taken me so long to respond, but thank you so much for your input!
It will certainly come in handy!
