I'm loving it! Like I talked about in the previous thread, I think it's really interesting to see your style which relies more on clusters than outlines and strong highlights, especially for this kind of tiny scale.
The genestealer, space marines and mk V Dreadnought (!!) have fantastic readability. The ork looks amazing when zoomed in, but I wonder if the fangs may be confused with eyes at 1x zoom.
The Space Marine with a power sword looks kind of like a woman with her hair tied up in a knot.
The old school dreadnought is my least favourite, but I appreciate that it's an extremely complex model to get right at this scale. And maybe that particular sprite suffers more than the others from the lack of highlights and clean breaks, due to its shape.
As for the tiles, I've never played SpaceQuest and so I don't know quite what style you're going for. But those computers / terminals look very generic and with the exception of the chaos star, I'm not really getting a 40k vibe from the tiles. Maybe it was an artistic choice not to make it too gothic or Giger-esque, but... yeah, I kind of want to see this with more gothic and/or Giger
Looking forward to seeing more of this. Mandrill on PixelJoint is going to shit bricks.
