ok. First of all thx for taking the effort of making a map. We appreciate that. I personally know, that it takes some effort to make a good map and so thx for taking this effort. Of course there are always some ways to improve a map. Cause no map is perfect at the beginning.
Here are some problems and improvements about your map:
First of all the Main Problem (cause it's the mainpoint of a map) is the path. Altough there is a big variety of defence spots all over the path i think that this path would be a bit boring to play, cause it's simply too monotonous and too long. Here we reach the next problem. The path is simply to long. If you play this map, it will simply never end.
So the first improvement (actually it's not really an improvement but a remake) is too remake the path. Shorten it, make the path clear and upload the map again.
Ok unfortunately i am not finished yet
Now we got to talk about the design and the background. If you take a look at some of the most popular maps, all of them have a clear background and a path that stands out of it. Your map unfortunately has none of both.
What do i mean with that. Your background is really confusing at the buttom of it, i can't even tell where the squares. The background is simply too colourfull.
So improvement: Make a clearer background. Often you don't even need big painting/design skills to do that. If you take a look at blueworld, there's no complex design(simply light and dark blue squares)
next problem: The path doesn't stand out of the background enough.
improvement: A good way to prevent this, is too make a border at the side of the path.
Conclusion: new/ shorter path and a clearer/ less complex background
