Thanks for your submission!
I really like it, but I was just wondering if it would be possible for you to create another option with Boa sitting curled up like this: http://www.cartoonstock.com/newscartoons/cartoonists/ksc/lowres/animals-evolve-evolving-evolutions-boa_constrictor-snake-kscn3114l.jpg
I'd like to see how it looks, so I can decide which one I like better.
Also, Puppy in your sketch looks very cute, but she looks a bit big? Compared to the fence and Boa. Puppy in my mind is a small, cute, fluffy dog. Not too small like a Chihuahua, but definitely not big.
