I believe she was referring to the fact that your title lacks a plural form for "tower", thus making it sound like there is only one single tower which goes by the name "Seven".
Also, for reference. Your maps are improving, but you still need a lot of work. Compare this quick fifteen minute mockup I made based on your latest screenshot to what you've got now of Alex's house:
Now, I'm not much of a mapper, I absolutely loath most of the VX tilesets, and didn't even finish filling out what details I wanted to add in. I don't even have the slightest idea what's supposed to be where, I'm only basing the mockup on the map you showed us. But, I think everyone here would agree that my mockup's mapping here is superior to your mapping, no boasting intended. Why do you think that may be? What differences do you see between mine and yours? What do you think you can do to improve yours?
For starters, add some symmetry. It doesn't ever have to be exact, but look how uneven yours is. You've got walls jutting waaaay out of position, and rooms startlingly larger than other ones despite being in the same hallway with a staircase that's clearly supposed to be centered. Organize your blueprint so that it makes more sense of an actual house someone would live in. Next, cut down on size to be a bit more practical. Hell, even the rooms in mine are a bit too spacious, especially the bedroom. Who has a bedroom the size of a living room? Once you've cut it down to be a more realistic size, fill up the blank spaces with some detail, as much as would seem appropriate if you were to actually be in that room. Do whatever you can to make sure the room doesn't feel empty, but without going overboard and adding so much that it looks like Enterbrain vomited its RTP onto your map. Thirdly, watch where your walls are. If you have a ceiling tile, make sure you include a wall tile to go with it, or else it'll just look weird.
