@mmKALLL I'll just comment about the first map, as that has a number of issues common to the others.
You seem to have mixed up the different terrains in a not very logical way. If the ground is soft enough and rich enough to have those strong earthy patches, it is unlikely
also to have patches which look sandy. Given the general lushness, the sandy (desert?) patches look out of place. I would stick to earth patches. Your cliffs are brown, but suddenly there's a patch of grey rock under the camp fire. As a general rule, try not to mix lots of different terrains in a smallish area unless you have a
very good reason for it.
That lower bridge has no logic to it at all. It looks as if you have to walk over your crops to get from one side to the other. Why would anyone plant crops like that? You can't weed them without either running to the upper bridge, cross over, run down again to get the crops on the other side - still leaving you to walk over them to get to the crops in the middle. Maps cannot be ultra realistic, but they do have to have a reasonable degree of plausibility. I'd put the crops somewhere else. A useful thing to do with all maps is to ask yourself : " Why is it like this?" Maps tell a story without words, so what story do I want it to tell the player and what story is it actually telling?
Your hills are not that high, (scarcely taller than your tent) so it is unlikely that you are going to move straight to desert, complete with dried up grass and cacti. This is especially the case where you have a broad river gushing down - that would naturally irrigate the ground. I'd have the tops mostly grass.
It is, I think, very difficult to mix autotile trees and more naturalistic trees and shrubs on the same map.
You have a broad river moving at some speed as it comes down from the hills, which suddenly narrows to a single tile width and is shallow enough to have what look like stepping stones to get across. This fails the plausibility test.
What the map lacks is coherence. It feels like a lot of elements have been jumbled together in order to give it "variety". Things don't seem like they fit together in any obvious way.
Don't be discouraged if you haven't yet got the feel of how a map should go. This only comes with a lot of practice, and studying how other people do things. Try and work out specifically why something looks good, not just why something doesn't work.
