Hi!
Looks like you've made a great start on this!
I have a few opinions that you can take or leave:
- Dorothy might be better smaller, to give a bit more contrast in size with the other main characters.
- I know these are just sketches, but just a reminder that, if one foot is behind the other, it should be higher on the page, unless it's a worms-eye view.
I think my favourite lion pose is the one where he's just lying there with a vacant expression, but that might not be dramatic enough... Otherwise I like the one like where he has his paws over his eyes.
In your latest sketch I think a smaller Dorothy would make it more dynamic. And maybe some more movement in all the characters.
I hope this helps!
