I'd agree with MtL on some of the texture transitions, but that map is looking really nice from what i can tell from your screenshot there.
Specifically, the river ford and the campsite stick out to me. I'd consider changing the ford texture to a darker, rockier texture, rather than the ruined stone brick one. Perhaps use that half grass/half stone texture there to blend the grass textures into the ford textures.
Also, i'd end the path/wheel tracks on either side of the ford, as they would simply wash away in a real river. Those shrubs in the middle of the ford would probably get washed away too, realistically. I'd tend to keep them to the sides next to the bigger rocks.
As for the camp, i'd probably change that dirt/stone texture into grass, probably one a bit lighter/less green than the rest of your grass (maybe even put a bit of plain dirt/stone just around the campfire for an added touch). Again, when you're transitioning between two different textures, try using a separate texture in between to make that transition less obvious. The hard part is finding an in-between texture that looks similar enough to both sides.
Also, things like trees/rocks/shrubbery can help distract the eye from the texturing.
Other things:
- vary those rocks in the ford some more. At the moment they're all the same rock object, and they're all on the same rotation and scale.
- make sure your river sections line up perfectly in water height and with the corner points, as i can see where the river is separated a bit there.
- use the tree placement tool for shrubs/trees if you haven't been already, rather than the regular object place tool. It rotates/varies the scale of them automatically, which helps them look less like they've been specifically placed. You can always go back and reposition/add/delete some later.
- consider adding some different types of shrubs in there.
Hope all that makes sense. It's really pretty good otherwise, keep at it!
