honestly its half assed.
its obvious to me you've kinda just drawn one brush of texture at random all over the ground and there are chances you didn't even bother to look for something different then the default ones already in the brush when you load a map
same goes for terrain, i can see on the land that there was no real attempt to form consistent cliffs or whatever and strange markings are left on the ground from you messing around with the different erosion brushes (especially in the water where i could probably pick out what exact brush left that mark)
decals are kinda strewn over the place with no real attempt at keeping scale consistent nor any thought towards placement (there is a giant overstretched acu deathnuke decal in the water for example that is hidden thanks to LOD)
the props are mostly the same autobrush pushed over the map and there is no consistency on where reclaim is and even there are some random giant rocks all over the place and some are havent even had the effort to rotate them around a bit to not look robotic or etc
the water/lighting appear default but i don't expect you to be able to rig that part up properly on your first go, we can save that for later.
yeah so in the end it honestly just looks very "made with supcom editor" and half assed, i get that its ur first map or whatever but the lack of love and care shows really hard here
this doesn't mean you need to use a world generator or something else to make a nice looking map, infact i think the opposite, the "made with worldmachine" can show too, you just need to put some effort into it.
