@Kristen-Lango Hi, Thank you!
Yup, I have been working on it...endlessly...but I'm finding this a really great piece for lots of trial and error. In fact, I'm even considering changing it into an internal illustration and then being able to make the cover more figurative. That way this one can be more literal, without the many-seasons and tree-wolves.
The colour palette thing is a very good point... I love using many colours, or variations on a bunch of colours, but then I feel like I have to hold myself back and limit it because that's what so many illustrators say to do. So it's really helpful to know what your reaction was to those limited colours on the girls' clothes.
Right, I'll keep going...
