Hmmm... It really looks kind of nice. For a non-import terrain, that is.
But there are two things that is bugging me off about it. The first of which is the brown river plant thingies, I forgot the English word for it. But I hope you get what I mean, anyways, they do not fit too well with the Ashenvale style. Then there is the background, you should have had some hills, or mountians back there as it looks kind of bare right now.
Oh, and there IS one third thing bugging me... No terrain can look bad with imports! And well, they really look bad without imports, for the most of the time.
