I have seen a lot of "animal portraits" on art education blogs, even some giraffe portraits. I will link up my last year post, because I believe it has some more details.
This year I had the students use oil pastels for the spots and background objects and then used watercolor techniques for the giraffe skin, sky, and grass!
Don't you just love that tongue and character of this giraffe
Oh that nose! such character and creativity
