Can't really add much to Reno's and A_S's excellent comments, some stuff i can remember from last time -
1 - most roof lines end in an unrealistic sharp edge, needs a vertical overhang under them.
2 - its a pain jumping up onto the grass bits.
3 - timbers are too thick and that would fall down in real life :smile: will prolly look better with some diagonal bracing (red line). Could also use something similar on other overhanging walkways.
1 - very chunky roof edge needs thinning down.
2 - needs a feature in here - barrels, fountain etc.
3 - on some of the bigger walls with repeating tex's you could ty scaling up the tex's by 2, it sometimes works depending on the tex.
4 - add variation by using a different roof tile on some roofs.
1 - those fades end very abruptly in a noticeable line.
2 - very thick beams need reducing. R_speeds are pretty low in this room so you can prolly get away with adding another set of roof beams.
3 - ditch the stone walkway and replace it with a wooden one with balustrading, it'll look way better.
4 - handrailing usually improves stairs.
Needs sprucing up with sounds.
Definitely needs a bit more texture variation for floors and ceilings, for the ceilings try m_ceiling3 and m_ceiling4 from TFC2.WAD
"is the cannon model used enough? Have I used it too much already? " - you could get away with putting in a few more, maybe have a couple together. Suggestion - make one cannon usable and point it inwards towards some part of the castle so that its possible to kill other players :smile:
"Are the barrels any good? Any ideas for something to go in the area with three barrels? " - more barrels :biggrin: barrels are ok-ish but could do with retexturing or steal the barrel models from Fishy's map.
"Should I re-do the skymap?" - seems ok except for the horizon which is sharp, needs to be more hazy.
"...and gets killed. Should I just restrict players from falling off at all?" - high parapets make it pretty hard to fall off unless you deliberatley jump over, any players that fall off deserve to be gibbed.
"Would it be worth trying to do water like in de_plaka" - maybe... although most of the wall parapets are chest-high so they'll prolly obscure the sea, i s'pose it depends on how high up the sea is.
/kicks you up backside to finish it :smile:
