I thought the foliage size increase did really good things for The Black Shroud, because it helped it look less like a rock garden, but in Ul'dah I think everything just looks a bit funny since it doesn't really match with the climate. The lime-green plants with the spikes on them in particular look out of place now, and the round, shorter cactii look very awkward.

The trunk trees also look very awkward with their larger size.

I don't have too much of a problem with the cacti being humongous, but my Roegdahn [sp] is shorter than their root system.

Here are examples of some of the offenders:
