Hi Mietze,
it looks impressive at first glance, the models are great, and i like the dominant colours! These are some of the best screenshots ever seen on TV3D. There are things you really need to consider though.
Firstly the global lighting is quite wrong. The skybox looks like it is full of clouds with no direct sunlight hitting the ground, and yet the shadows from your PSSM shader are crisp sharp. At the very least, with that many clouds, the shadows would be blurry, but most likely they would not exist. When you have a single point light source from the sun on a clear day, things are pretty simple to simulate. However, here the whole dome is radiating some light, because the clouds diffuse the sunlight that passes through them. This is what "ambient" lighting factor is for, and it does the job to an extent, but regardless of amount of ambient light you cannot have shadows as sharp as this. I would advise you to make the sky look a little more realistic to match the shadows, and probably decrease the fog too. Make an area of the skybox clear of all clouds so it just penetrates through, and so the sun itself can be clearly seen. I'm not sure how viable that solution is for you in terms of art direction. The other solution is to blur your shadows.
The next thing that popped out was the specular strength. It seems to be concentrated (ie focused) and the reflections on the snowy hut for example (pic uber05) seem to be unrealisticly overbright. This would be too much even if there was direct sunlight, like mentioned above, but direct sunlight would balance out the scene lighting more. The snow texture is also watery. The solution is probably that you need to decrease the normal map amplitudes (make it a little flatter) and decrease the specular intensity. Also increase the specular reflection focusing (cant remember the right term right now for it, but you can make the circle where a point light reflects really really wide, so do that). The other buildings in the background should also reflect some snow, as well as the trees. They look almost non reflective right now.
As for the models themselves, some are better than others, but generally very good, however I don't think there should be snow under a roof (first picture), and you may want to add some snow piles around the edges of the buildings (snow falling from roof). Also, if the roof is covered with snow, it wouldnt have such sharp edges. Maybe if it's iced, but then you need different textures. Snow would pretty much fall down a roof such as that of the building in the first screenshot.
So much for now! Keep up the good work.
