I didn't intend to make the hallway appear darker but I think it turned out pretty nicely. The Castle Center itself is probably the most intimidating level to texture so far. Nearly every single room has it's own set of textures.
Tower of Science
I was working to put a chained Medusa based on her Legacy of Darkness appearance in that tank. I liked the idea that Dracula either turned villagers into Gorgons or kept Medusa herself chained up to somehow use her as a means to control the Medusa Heads (In Castlevania 1 you did have to fight a lot of them before confronting a statue that turned into Medusa herself).
Now that I'm replaying Castlevania: Order of Ecclesia on DS however I sort of see a resemblance between this creature and Rusalka, the boss from Somnus Reef (Link). Since I am trying to tighten the timeline (as far as that is possible by altering textures of course) I'll likely go with that interpretation instead.
So here's a screencap of something that probably won't make it into the actual pack:
Heck, at one point I was considering putting Trevor Belmont, Sypha Belnades and Grant Danasty in the different tubes as a way to explain the fakes in Symphony of the Night and Portrait of Ruin.
