Feedback on new design for a tshirt!:)

[Archie92]

Hi everyone, just a quick little thing to ask for some feedback on a design I created for a tshirt. It is just a little joke about a horse turning into a zebra. Any comments/suggestions would be hugely appreciated!!!
The design is here:

I like it, though I think it would look better with all of them on a single horizontal axis so it reads across in sequence.
