This is great Perihelion! It's exactly like looking at a screenshot of a well-pixelled SNES RPG. Helm's edit on that metal is very interesting (I'm going to study it because it's exactly the type of effect I've tried and failed to achieve) and yours, while not as quite as smooth, is looking heaps better than the last update!
One criticism though, I think the rows of rivets (holes?) between the floor tiles are confusing and strange, though I cannot pinpoint the reason. The rivets appear to be in a gutter between the tiles, and this gutter is about as wide as the character's foot, so the floor must be really uneven. It must be a pain to walk on that! Why are there so many rivets to hold down just one tile? Right now there is no transition between the grates and the rivets so it looks kind of flat and out of place...
I'm very new to pixel art, so this advice might be worthless garbage. I hope it helps though
