I already commented this on youtube, but it's worth saying few words in here too.
This is easily the best Finnish (or Finnish-like) track made to this date. Framerate is very good even though the stage is 18 km long. For my computer, there is only a few parts (the very wooded place and about two places where there is a lot of bushes) where the FPS drop. But it really doesn't affect my driving.
Crests and jumps are very real. They are not too sharp, but very smooth and well done. There are a couple of jumps that you really have to take carefully (even brake a bit before the jump) - not every jump is possible to drive flat out. That makes it very real.
Corners, cambers and ditches are very well made. There are many great corners and corner combinations. On some parts the ditches are a bit sharp, but it's understandable (sometimes in real life they are also sharp if the ditches are brand new or they've been "fixed" - for example 2008 Rally Finland stage Väärinmaja had these kind of ditches on one section).
There are also few "places", aka crash corners that catch you very often. Just like a real Finnish stage in this sense too!
All in all, a very good track and I'm looking forward to your other stages too.
