Honestly the environment/foliage/terrain is quite horrid. Well, I can see how enthusiastic you've been in the making of it all. The terrain being very big and the amount of vegetation being quite large. However the quality of it all failures.
You have these strange, I don't know what it is, reeds? spread out all over the place. The rocks really doesn't do the build any favors. Some spots are way to plain terrain-wise. All the trees are bad. The multiple terrain styles used makes the build look very unconsidered and random in a bad way.
The actual dam is quite a nice set even though I think the style is quite off. Would had liked something more clean and not as pinnacled as the front is. I mean with those ramps being very attention drawing and abit futuristic looking.
Man, It's quite a big creation and it's not as bad as I perhaps say it is but you got lots of stuff to work on.
