In response to a few requests, I have whipped up a few 16 x 16 hallways to connect the tiles in Sci-Fi Tiles 01 and 02. Again, they are without watermarks or tags, so you can turn them as needed. I included a cross, a "T", an "L" and a straight hall. Hope this help make some interesting maps!
I included all versions here for free for everyone to check out.
