Nice, these are looking good. Your swamp map is a little bare, and it looks a little like a map of some islands rather than water-logged swamp-land. The colors are good, though. The grid is a little distracting, but that might be the brightness of the white on such a dark map. Same for the mushroom map, although that one looks better in terms of the layout. I'm not sure the mushrooms, ground texture, and those more "scientific" (?) elements work particularly well together at the moment, but I just love those mushrooms!

Your first 2 maps, the imperial prison and command center, look great; I just want some labels! ^-^ They're very clean and the level of detail is good. The only critique I have would be the blood (if that is blood), doesn't really fit with the excellent detail of the rest of the map, and if that is blood, all the 'furniture' in the room is remarkably well-aligned and upright. That is, of course, based on my assumption that blood = rampaging monster of some kind ^-^; Good job so far, and looking forward to more!
