Here's my sketch before I move to the final. I'll be rendering this in pencil then scanning into Photoshop and colouring in behind in the pencil.
Sooooo much reference needed for me to get this basic looking image together, as I'd never drawn pretty much everything in the image
I wanted the text to mirror the 'falling' of the character by spacing it out in vertically staggered slices.
I've designed this to picture book dimensions and have accounted for the gutter in the middle so nothing of importance is cut off.
Some process stuff:

I ended up doing a basic blender model of the castles to help me visualise camera angles and the like. I find this a super useful approach for interiors and buildings.
I flipped the composition eventually so the griffin is facing right and so that the text can be read left to right.
Here's the two point perspective guides put in place.
I wanted the reason that the character was escaping the castle was to save the captured baby griffin and return it to its mother. I thought about cropping this in so this can be clearly seen but I figure in the context of a book this would be emphasised in another section. I also felt that showing the griffin in full would make a more dramatic composition.
