I'll take a scale photo in a moment. I know I always like to see, so I figure others do too.
As I said, I'm intending it as a free trader for Venus. My Parrotman airships are built as Tri and catamaran style balloon set-ups with decks. I'd always intended to do at least one trade vessel that was a blend of human and parrotman styles, so when I found this in a cheap shop it was the perfect base.
I'm thinking, add crates, barrels etc as a half layer across the top deck with partial canvas. Then add walkways and railings to extend the centre and allow figures to move around it. Create a bridge, change some details and repaint. I don't think it needs much more for my plans.
