Is there a free drawing app for the iPad Pro that is good for doing pet recolours. Want to try doing it myself and starting from scratch learning so don’t want to buy an app if I am going to suck at it :p

Also where do you find the large pictures of the pets used for editing?

This thread may be helpful if you're seeking full size artwork for re-coloring or editing purposes.

link It's a directory of the artists who drew individual pets on the site. I'm not sure how up to date it is though. Keshi used to have a thread of full size pet bases artwork that people could use for coloring, graphics purposes, but that thread was up years ago so I'm not sure if it's still in the forums.

As for art app, I use Procreate, but that's pay. ArtRage which I've used in the past is about 5 bucks US though, and this one, is free on the app store Disclaimer that I haven't used it so I'm not sure how well of a program it is though.
