In my opinion this map would be a lot better if you:
1. Make the log bridge stone or wood (i.e. an actual bridge so you can fight on it without pulling your hair out).
2. Put in a land bridge, or a regular bridge at the fjord (or something that makes it so melee can cross without leaving their asses open to ranged for a good 5-10 seconds)
3. Adjust the spawns like they are in the picture (black dots) and make the master of the field like the red dots.
Also maybe a nice rustic log cabin or two for cover from ranged and to give the scene some atmosphere.
Now mind you I have never made a map for cRPG specifically, though I have done some for other warband mods, so take my suggestions with a grain of salt (and I am also just a plain old dumbass), but I see no reason why this map couldn't be great with just a few minor changes.
Also, there are more than a few people who blame their clan-stack losing (or general losing streak) on the map for reasons related to ego, so you should only really listen to the people that can provide constructive complaints.
Edit: Now that volcano map is one of my personal favorites, but it needs bigger doors at spawn (so many fuckweasles teamwounding) and either a net to catch the jumpers, or someway to auto-kill anyone that jumpes down with a horse.
