From what you've shown on the screenshots, I think, vegetation is quite authentic, too. So this is no complaint, it's more some general advice – it's part of my series "giving good advice"
. This time, it is about vegetation. Actually, there is quite some variation in that respect towards the regions of Germany. I have found a very interesting map showing the land use in Germany:(Here is a legend)
What can be seen is that there are quite significant differences in vegetation and land use. Forests are unevenly distributed in Germany. Whereas the northern federal states do not have very much area covered by forests, their percentage is quite large in the south and southwest, ranging from about 10% in Schleswig-Holstein to about 42% in Hesse and Rhineland-Palatinate. Additionally, there are differences in whether the forests are coniferous or broad-leaved. For example, forests are mainly coniferious in southern Brandenburg and in the Black Forest. It would be nice, if some new coniferious tree models from Scandinavia were used instead of the old low poly trees. The dominating coniferous tree in Germany is the Spruce rather than the Pine, the latter one already having a decent (although relatively mediterannean looking) model in-game and thus it might have been used more often. With the assets from Scandinavia addon, there are more models that could be used, also such that look more like Spruces.
Besides, I assume, farmlands tend to be larger in Eastern Germany for historical reasons, but I cannot say for sure whether this is visible in terms of landscape. Another interesting thing is pastures - they can be found e. g. in the Allgäu or East Frisia / North Western Lower Saxony. I wonder if you paid attention to this when you built A28, the landscape is very flat and there are lots of pastures with cows on it.
