Only today I continued working on this; last days spend thinking about it and trying to visualize the scene, but now I finished most of the modeling, I think:

The tree leaves were a bit of a challenge to figure out, but I’m happy with the result:)
Still a minimal amount of texturing to be done (mainly the shirt) and placing everything where it should go.
Don’t think I will have time to do the spaceship, but we’ll see.
