Rough Illustrations and Layouts

Here are a few illustrations and layouts I've been messing about with, I think I want to stick with these illustrations and play with them in the layouts, I want to keep the colours pretty muted nothing too strong. I love the wallpaper from the third photo so would like to incorporate it in some way if it works well with the copy and illustrations. I also want to play with the copy like I have in the last image here but it depends on wether it works with the illustrations could be too much altogether.
