Sorry for the late reply, I know it sucks waiting for feedback.
Anor Stronghold:
Remove 50% of the light and smoke effects.
Otherwise, looks good, will probably play well right off the bat.
Hori's Hold:
Stairs leading up to the flag are not working walking upwards. Recommend you replace it with some other kind of stair. It is also very easy for defenders to just camp the flag room. You need to put in a second route to it, or a much short one. Very creative, and I like it, hope you can make it work.
Orlaugg's Hold:
Nice scene, altough I think you have perhaps gone overboard with the different styles (viking carribean theme). Make ramps for attackers when leaving the boat at the main spawn point. There is tons of night lights that fill no purpose, you should remove most of them. Also a wall to the right not blocking anything. The right side also have a passage (an awning), you should change that to a ladder insetad, looks bit silly when people run around on cloth in the air. Some invalid items, you should use cRPG for a base module when making maps. In the flag room there is an armour just floating in air.
Rione Stronghold:
Looks good, nothing to add.
Woofalls Castle:
Looks good. I'd move the ladder that leads to the tower, down to the walls instead. Also I'd like to see a second layer of defense, around where defenders spawn (some funnels for attackers), otherwise I fear that defenders will be overrun very fast.
Will add Rione Stronghold to the next patch.
Good job, happy hope you can update the maps soon!
