Oh man this is gonna be so awesome

Loving the sprites so far.
Ornstein's legs are a bit too much though, he looks more like a ballerina than a fighter.
His ploom is a bit "liney" too, you should worry more about form than single pixel detail.
Regarding the tiles, you have a great structure to build on here.
Is this going to be something playable or just as an art piece?
Because this affects what you can do with lighting and such, and also the readability of that big club thats hidden behind the pillar.
As it is, the floor texture is too repetitive and noisy.
In shadow areas, let it get a bit darker again near where it meets the wall.
I don't know if its worth saying about all the outlines on the pillars if this is an early copy, but I hope you plan to deal with those too.
With things like highlights on your stairs, try to blend them along the top surface a bit.
Top of those dark blue floor tiles could be a bit lighter in general actually since I can barely see the dark lines
I think bricks in shadow could be covered with more of that shadow shade you have.
Try to use suggestive lines on the brick walls rather than so many obvious outlines.
And then just have the odd brick that is a different tint than the rest, some that are slightly sunken in/raised compared to the rest etc.
You need stronger AA on the estus flash and the base thing they sit on.
I hope you're planning to do something with the health bars, those black lines aren't doing you any favours.
