Have you been to oohmoon.com? Katie Moon is a talented illustrator who’s offering up 1 illustration a day for a year. She’s had some gorgeous stuff, she did a whole nativity series over Christmas time that I saved for use next year.
I am just in LOVE with this Noah’s ark series though. The colors, the to die for illustrations. SO cute. The download is only free for a day then it goes to $5 (totally worth it) Check her out!
