Wow! I'm grateful to everyone who's posted on this thread for making the sketch upgrade possible -- the cleaned-up sketch is a vast improvement over the original. The added architectural detail creates a much stronger sense of 'place' to the drawing, but what I find most impressive is that you were able to keep that same degree of wonder in her expression while taking years off of her face. I think you'd be an excellent choice of artist for the book, if/when that comes together; good luck!
