That castle really is meh. I expected a ton of Archs and really high, sleek tower, something like Anor Londo, since it is what the Novel described. At least make it as cubic and imposing as Sen's Fortress.
Poor move, artist, poor move.
Well it still convey the idea it's a huge castle, but it lacks the magnificence. And the Archer. Never forget those assholes Archers.
