Large, roomy and about as close to "predator proof" as you can get! Some pics of the inside set-up would help a lot, as would some details on the actual build (dimensions and such.)
This is a fun read ... I LOVE the "Hunting Season Logic!" And as far as making it "cute" goes, there's a big, blank slate, there. Maybe add a little lattice paneling with some edible vines, some flowers a bench or some interesting wall decor. They would go a long way to softening the "fort" look you not thrilled about!
