the only thing that really bothered me:
way too many camera switches. you can barely walk 2 steps without a change of view.
i think this will crush your gameplay a lot and it will start to get annoying very fast (cant see enemies, hard to control, get pushed out of the view when hit or attacked ....).
try to reduce that with smart level design.

i would also rework the textures to fit a color layout. if you use photos you will either have to set a "null lightning" for all textures and use the game engine lights later on, or you will have to rework and tint them to match a color scheme upfront.

i liked the old ResidentEvil games a lot. and since i am not alone here, you might get quite a bit of interest generated all over the web.
