This lego set is just amazing! It is very different comparing all the sets i have so far made experience with :) I'd say its very much about ideas - that you don't find very often in usual lego sets. What is very nice about the set is that it nice and firm, parts are not falling apart... Very nicely designed :) If you are not really experienced builder, be very cautious when building! Otherwise you will have to revise your tree a lot :)
