I love love love love that house, the design of it, the colors, everything. If I had to think of any crits... well, do you really need the line loops on the inside of the flowers? They do give a nice subtle little bit of curvature to the petals, but it seems all these flowers are gonna be seen from quite a distance anyway.…
If you really want a New Zealand bush vibe, you'd need to add some Pungas, Nikau's and maybe even a Kereru for good effect. At the moment, the trees and flowers (although awesomely executed) are non-descript and are disconnected from the Marae.
