I like it! But, maybe consider adding another set of steps on the side of the deck near the kids' play area. It is a large enough deck that another set of stairs further away could be a sensible addition. I too feel the jungle trees are a bit off -- size and world location. The family lives in a nice, but large, house, so to have trees that are taller might be a bit...much. When I build in each world, I tend to use trees that have been used in that world or would be similar to what that world's "zone" would grow best. Not that you have to do any of this.... :D
