The illustrator, Judy Belchin, is a UK-based graphic designer, craft demonstrator and artist/illustrator extraordinaire. She has dabbled in the world of television, logo designing and even needle-felting, so has a lot of background and experience in the creative world.
Art Nouveau was popular at the turn of the century and is identified by its ornamental curves, whip-like lines, and asymmetry- some great characteristics for colouring book designs. If you're into blending plants and flowers, take a look at some of the pages in the book and notice how how leaves and stalks are heavily featured throughout.
I'd recommend this book to colourists who have a passion for art; particularly sculptures, statues, stained glass, and nature. I'm sure fans of historical design would love it, as it seems to be very true to the period.
Here are my finished pages. I absolutely LOVED the stylised typography at the back of the book, which I'm now using as my signature on all blog posts :)
