Indeed, I'm aware of that. But such a detail is not worth the transfer size (as I'd have to add 4 more tiles), moreover this is a competitive map especially designed for clan-wars so I can't help but avoid concept-art elements. Which I did, mostly...
The main idea was to make a map that's competitive and looks relatively good at the same time.
Simply great, I tried the map and I like it alot, I found some flaw though. Some snow tiles had lacking shape detail, there were sharp edges on them, I hope you know what I mean. Except for that it's a excellent map.
