Crazy Ponies - how its done

Was planning on making this since I started doing these posters.
Why? You ask. Well, mainly because I like seeing how people come up with stuff. I find it really interesting to see how something comes together.
This isn't technically a tutorial as I didn't lay out the exact steps I did. I suppose this is more of a demonstration as to how I made these posters.
I hope you find it at least somewhat interesting. .
Cheers.
