One of the things that pleased me the most about LoS was, of course, the aestethics. Not just the graphical prowess but the art direction. A few notable things (SPOILERS of course):
- in the bog level, the first time you take a stone stair - the texture quality is insane. I live at the foot of the mountains, and there's quite a few walks that look just like that around my area. The wet rock effect was simply fantastic.
Then the shrine. The wild growth and the gothic style definitely clicked with me.
After the fight with the troll, as soon as you leave the graveyard, there's a stair going down leading to a slope and a life fountain, with water pouring down the side of the mountain. Everything is illuminated by a small bonefire, and that screen looks just beautiful. The camera pan on the following platforming segment is the icing on the cake.
- entering the great three in Pan's level - the scope was amazing, and the camera work fantastic.
- the lycan territory was somewhat weaker than the rest of the game, but there were a few amazing shots there too. The section where you fight the second warg and have to ride him till you climb the vines looks beautiful. At the beginning of the Dark Labirinth level, as you climb down the well, the water effects are absolutely gorgeous (some of the best videogame water I've ever seen), and the swinging section looked almost photorealistic. Awesome motion blur. Too bad the framerate was so terrible in the actual dungeon.
- the entirety of the fortress/crow witch level. Just borrowing a screenie from GAF:

Enough said. It's bloody incredible stuff.
- the game definitely peaked in the second half. Almost all of the castle is fantastic (the Butcher's kitchen is an incredibly atmospheric set piece, as was the refectory). Olrox's arena and the entire fight were incredibly cinematic.
Guess I could go on for a while. So many great sceneries in this game.
