It really is a very good book cover, "walking with the sun" must be a very interesting book, the art you used conveys a very spiritual message, and the color palette is very nice and harmonizes with everything, and I am fascinated by the How did you achieve the transition of your hair to the constellation.
Hi my friend! Thanks to write me, I am very grateful to receive feedback like yours, its encourage me to keep working and drawing. This illustration is not the cover book, just one of a serie of illustrations that are going to be inside of the book. So there is more illustrations like this. :) Check my previous post if you like to see what I have showed until now. Have a wonderful day my friend!
