I'm trying not to be too perfectionist so I decided do go ahead with the shadows, though realizing there were fair chances that the ancient paper I was using (Fabriano 1947) would be too brittle for their softness (I was playing with the composition, mostly) and for tones in general... So it was, I'll start again on better paper.
The lime trees here are giving away their lovely seeds and I'd always wanted to paint them.
