Drawn from a photo taken when strong sun was shining into a darkened room, hitting the flower and creating some interesting lighting.
It doesn’t stand up to close scrutiny with all those grubby pencil marks and scrappy lines. The graphite from the underlying pencil sketch gets trapped and sealed by even a light watercolour wash. Even if I’d rubbed most of it out before painting I think some would have shown through. There must be better ways to do the initial outline sketch.
