Sketches: A New Possiblity

As work on The Kingdom Chronicles: Book Two is working toward it closing chapters and final edit, I'm beginning to ponder on the idea of adding sketch art at points throughout the book. Of course this might also add up to a new edition of Book One with sketches added. It's possible, but I'm not swearing to it yet. What do you think? If The Kingdom and the Crown were re-released, which scenes or objects do you think would be interesting to add sketches of? Comment below please!
