So here are the final few Work In Progress photos. I'll post the finished item up separately.
I'm pretty pleased with the way it turned out.
A tip for anyone who's thinking of trying papercutting - don't draw out your picture with pen!
This was a bit of a mistake as it made my cut line virtually impossible to see and I ended up cutting slightly off the line in most places. When you're cutting over a pencil line, the cut line shows up very clearly and makes life much easier.
