A very nice set, providing exactly what it promises. Definitely worth the money. There are a few minor niggles about this set, but that's to be expected.
The hill parts don't sit too well together. If you alter them to use the 'bobby pins' as described for walls in the basic modelling manual, that should solve that problem, but do it before you start putting it together!
The bridge and hut are a bit 'cheap and nasty' compared to other products from Fat Dragon, but perfectly serviceable in spite of that.
The trees are an inspired design, however each tree takes quite a bit of card to make (something like 2 trees from 13 A4 sheets!) and quite a bit of time. You're unlikely to furnish an entire forest from these!
All in all an excellent set.
