iPad mini for animation and drawing?

I’m learning how to animate and want to get something else besides the drawing pad I’ve been using for my Mac. I’m not the biggest fan of it as it just feels a bit awkward.

Would the iPad mini be a good upgrade? Is the screen big enough? Or should I stick to the classic iPad?

I want something a bit on the smaller size as I do travel around for my work and having a full size iPad and a MacBook seem like it may be a bit much. But if the iPad mini isn’t good for what I’m looking for, I’d Goro the larger size.
