I very much enjoyed walking around it... but unfortunately just from the walk around I have some comments that, to me, are very important.
1) Overall the theme is FANTASTIC, but several of the pathways between areas are far too small. Specifically the right B-C path (from B). Overall the size seems a little on the large side and needs to be broken up, which leads me to...
2) Point B. It's beautiful, works very well with the theme... but the pits of doom are absolutely map-ruining. I died four times just jumping around B while alone in the server trying to navigate. I can't help but think that it will get very frustrating for people in actual games, much less competitive play (which I very much think this has a shot at). To remedy, I'd say that you should replace *most* of the holes with rocks. Yes, rocks. Pull a furnace and drop rocks wherever the hell you need to just to block sightlines and in your case plug holes (<33 Youme
). Replacing the ice-holes with rocks will both bring the map a tighter feel but also allow for more interesting vertical play...
That said, leaving the death-pit-water-stuff around the edges and in maybe one or two obvious places is just fine... as long as there's signage of some sort. ^_^
3) OMG the theme is AMAZING. The only thing that seemed to not read well was C with all of its odd architecture... I love the ice cave idea but you need to seriously think about how the structures would be in nature to make them make more sense... a lot of things lack logical supports and have sharp angles, which is very out of place in nature IMO. Also, maybe add *some* rocks and whatnot to the cave to liven it up a little and place some water somewhere in the bottom so that there's some "meltwater" to have it make sense.
Overall I absolutely LOVE it. I can't wait to get into it on a full server, because honestly I think that this map has a TON of potential! >:3
