Yes, indeed. You need to fix your scaling. The people are the size of a whole house. Alot of floating doodads, fix this by clicking on a doodad and pressing CTRL + PAGE DOWN. Bad fog, also. You need alot of practise. The tree variation you chose is quite bad. You should have a sense in which trees fit and which don't. Never scale the water model, instead carefully place a whole lot of them and align them good, to get a nice touch. Some doodads, just look out of place. The underwater doodads don't look very well. Lose the orc walls and scale the grass, its huge.
