Right now I have a big problem with how elemental displays elevation. I realise we are looking at stills and if the camera is moveable and rotatable we will be able to move it and get an understanding of it. But right now looking at the stills I find it really hard to see where the hills start.
ok now sorry I linked to IGN, would like to link them in here but im feeling incompetant

these two are fairly typical of the problem. As you can see its not a problem when the light source is behind the hill and throwing a shadow, but when the hill has the light source in front of it its very hard to get a feeling of where the flat ground is.this is shown in the hills on the left of both these images.
Now perhaps the elevation wont have a gameplay effect and so it wont be that critical. But I find it visually jarring, it gives me an impression of going from a 2D map to a 3D map.
