Looks good Laurie! I watched many monkeys swinging round the trees near our old house in South Africa, keep an eye on the tail movement, as they use their tails for balance and to curl around objects for support.

I know it's a blocking diagram, but the tail seems to point up most of the time right now. When leaping it is more likely to be level'ish with a curl on the end...

Things I would keep at the back of the mind...Squash and Stretch!!!

Nice sketching!
