notes:

A good object, but less detailed than it could have been. Your
parameters were not very expressive. In fact, you really don't have a
continuous parameter in there. You listed the tree color as your
continuous parameter, but that's really a material parameter, because
it's not changing the geometry of the scene at all.

Also, you did not obey the scale and rotation constraints. Your scene
does not fit inside a unit cube and you have not modeled +Z as the up
vector.
