1) I would pull the red a bit more far, just to be safe, I think the chance of agro is 45% with large armies.
2) I would add some trees to make it that camp more deep in the U region, I think it may agro for a wisp scouting, but with low chance, lets say 20%, just be safe. (agro of wisp scouting is very penaliced, it hapened in my map in the 3rd contest
I tend to be hard pointing this stuff, but hoping that at least your maps could reach Blizzard with no need to do updates
3) IMO, I would remove the goldmine for competition, the one aligned with the tavern simetry line, because it seems redundant, I would put there a shop (goblin shop or marketplace) or a merc camp.. merc camps are too near. or put the goldmine in the other corner so to not have 3 mines so near and aligned.
4) also gob lab to near gob shop, is like take 2 places in a row IMO.
