Gorgeous shapes - I love how angular it is, it's the most striking characteristic of the cheetah and you captured it perfectly. Using polka dots to stylize its pattern is a very nice idea, as well as the addition of blue.
I love the shapes. It's just so fun to look at how exaggerated their backs look- even though you didn't exaggerate. That's what I love about big cats. They have this great, slinking movement when they walk.
