Not a bad start, but the terrain is still lacking.
For starters, the decoration in the map was sub-par. It's not overly empty, but there is a lack of decorative doodads not including ones used in masses such as trees. The choices of doodads were fair, but more would definitely be better. Be careful not to spam though.
I noticed you didn't used random rotation doodads at times. This makes environments look very unnatural. You have repeating rocks near the bottom left of the map and repeating shrubs bordering the river.
I see you've edited the tile order. Well, I'm glad you know how to do that, but you didn't particularly do that in the right order to make the map look better. Rough dirt over grass simply looks peculiar. Other than that, the tile usage was fine but there could have been more of a mix.
The use of height tools wasn't very good either. It simply was flast with the exception of bit's of raised and plateau'ed areas. Try to make the land not so flat, but there really isn't a need to make it lumpy.
The river area didn't seem too convincing it was a river. There are heavy waterfalls... falling into shallow water? And that shallow water didn't have waves and it the majority of it had straight line coasts.
Map rejected, rated 1/5. The terrain could be acceptable for a playable map (Though not this small), but for the sole purpose of showing it off, it isn't acceptable. The map also isn't very useful as a template either.
