The map looks great with two exceptions:

1) Bogie already took care of the beach sand question.

2) The blurry grass detracts from what otherwise is semi-photorealistic work. It would make a great improvement if you boosted the resolution on the fill so that it looks like grass or if you used a better grass fill.

I also notice that there's a dead body there that looks more like a motorcycle.

You might be able to fix the sand problem by putting the same texture over the beach area and then darkening it ... if one can do that with CC3+. I've forgotten if that's possible with CC3+. It's what I would in FM8. After that I would give the beach sand a feather. I think that's an edge fade in CC3+.

Nix für Ungut!
