I think I prefer the first one, if only cause the sprite looks better and cellshadier. It all depends on the art direction for the entire game, I guess.
I also have to be a little critical of the background in this screenshot. It looks very...clean? And pedestrian. Or maybe it lacks detail. I understand it's a very early screen, obviously.. And I guess it's possible that this particular part of the castle is supposed to be exactly like that, but I want more intricate details, like on the wooden rail. And the chairs look odd. I hope we'll see more detailed architecture, statues, crumbling walls and gothy atmosphere.
