I like the building and tree models, the terrain textures/colours, and the lights too. Yes, the character is not really a nice guy
What I don't like is the water from close look, the grass entities, and the very rare tree and other vegetation placement: use much more (some hundreds), or group them at small areas instead of the consistent positioning, it would be more natural - and it's valid also for the grass, use a lot in groups or do not use. And those high slope hills are also a bit bare/lifeless. Use more bush entities, they are low cost in performance, but gives more life to the level.
But the overall concept is okay, I think these are easy things and only detail refining I mentioned above.
