The creators behind Mozzi's Adventure Mats saw how much fun their one-year-old was having with a play mat. However, everywhere they looked, the play mats they found looked the same. Uninspired by those existing play mats, they came up with the brilliant idea to theme their own mats to certain cities using a different design aesthetic.
The creators asked me to step in to create the maps. After figuring out their style, I went about creating themed maps, hand drawing the elements for the right feel, and then combining that with the speed of digital techniques to finish the maps over the course of one and half week's working time - just in time for a Christmas sale. The result is a beautiful play mat that encourages meaningful play time with a child.
Illustration for pitching a children's book. Your editor and art director will likely want control over this aspect of producing your children's book. It isn't standard practice for an author to pitch a book with illustrations since a book goes through a fair amount of editing before it's finalized, illustrations included. It is rarer that an author will choose the illustrator for their book.
