What's demanding is the polycount. You could do alot by improving texture quality for instance.
Looking at this screenshot, what strikes me most is the poor quality of gras sprites. It's too big, the texture is to blurry and the alpha map too strict, meaning there is no soft border.
That's something that could well be improved at some point of the development, it's not top priority.
However the sooner something like this is changed the sooner screenshots of the environment will look pleasing and gets people's interest.
Same could be said for the gras texture on the ground. It's good for now but needs to be improved at some point.
Character models already look pretty decent.
I'm a bit unsure about the foggy bloom you chose to implement. I think it would look better without it.
