I think well enough befor i type (also my english is rather bad too (i'm 14 and from Ukraine you see), i said it looks bad due to the fact it doesint even look like the actual pool and 168 polys is too low for a building.
i understand that it must be hard to make a model (playing around in my cuz's 3dmax i couldint even figure out how to make animations or add textures), but this model is very low quality and wouldint even be usefull in a game (and why make a model if in a game it doesint look on par with the other models?). sorry but it does look bad and me saying "good attempt" aint going to help any.
also if you really want to make it better then look at the original building.
