Great topic, thanks!
I'm new here and still finding my feet, but I'll do my best to get an entry together that doesn't make me feel too inadequate.
Update - finally had time to make a start. Critique welcome, I don't bite.
Update2 - final updated. I was going to put Lyra on his back and clean everything up, but I have a lot to do before Monday.
I've enjoyed this a lot though, will definitely enter these as much as I can from now on.
