My sister's Wedding Illustration

My sister is getting married soon, and she asked me to design her wedding invitation by making a caricature of both her (and soon to be her husband's) dogs.
Well, I do admit I'm a little too much effected by Coyote's look since I'm sketching him, but still, it also helped me in getting the exaggeration poses I was looking for.

Anyway, here's the sketches I've made as I moved from the roughest sketch to the final rendered painting.
