The problems with colors, textures and contrast remain.
Technically, the tiles fit very well, with the only issue being the gaps in the outer walls.
The walls look unnatural because on a starship there is a strong expectation of continuous, tough and redundant airtight enclosures, and the thick light grey outer walls look like they should be one of the most important such structures (in fact, they are probably the main ship hull).
So interrupted and missing walls are bad, but you are already able to fix them by using filled exterior corners (similar to the current interior corners) instead of the current wall-end braces, and by adding walls where they are omitted.
In the new examples the hexagonal floor tiles are well designed but incompatible with the square grid (deliberately tall or wide hexagons would look better than the current wannabe regular ones) and even more incompatible with the rectangular room shapes. However, the exaggerated edges are a good starting point to improve rectangular floor tiles.
The dirty concrete (?) texture, while not bad by itself, is very out of place: dirt, moss and cracks should not exist on a starship. Use it for ground environments (roads, airfields, courtyards...) if there are any.
