Nature into model 3:

Canopy's can have stalls in. Above them could be a roof top café if stairs is added.

Furniture could be yellow and green, ivy could hang and have many fresh plants for decoration, toadstools tables could also work with the theme and help the stalls on the lower levels to blend in too. I would like a rooftop café so furniture is an efficient way to introduce this theme of the Woodlands. However I would like it look quite classy therefore I may have to rethink the Toadstool idea as it could look cheap and tacky.
