I've only really taken art direction from Julien, and there's usually a fair bit of screaming and crying involved if I have to draw something for him ^_^; Assuming you don't have the same objection to my 'childish' style, if you could sketch out the compositions and send them to me along with any notes you'd care to make about colours, details you couldn't render, etc. I think that would be a good starting point :)
