MY INTERIOR, HELP ME IMPROVE MY DESIGN

You have a problem with the roof : the tile that separates the different rooms, it should be a roof tile, different from the walls ( I don't know xp so I can't tell you where it is on the chipset). Also, yeah, the hall is too big or too empy, fill it with plants, furniture, whatever pleases you, carpets wouldn't be a bad idea, in the rooms also.

What are you trying to work on with this? The functionality? Or visual appeal? Both seem to need work.

Try envisioning your design as an actual real-world building. What would realistically make sense for its overall layout? Interiors are never just featureless open settings. Condense the room with wall shaping, furniture, doorways, windows, objects to interact with, etc. Always consider the realism, atmosphere, function and detail when working on your map design, or your game may seem lifeless and stale!

Here are a few examples I think are pretty decent:

Doesn't hurt that every single one of those was done with a fucking amazing chapset.

An amazing tileset doesn't necessarily equal an amazing map. These maps also have had thought put into them...thoughts like what Blindmind was mentioning. XD

That's looking better already! The bottom floor does look a bit empty, though...

The friend I'm making my game with gave me a tip the other day that you might find useful:

"You don't need big rooms all the time. The smaller they are, the less empty space you need to fill, decorate or give context to."

Now, that's not to say you should make TINY rooms for no reason. But it's not a bad idea.

What are these ones from? Other than the Badluck one?

You still have a lot of progress to make. It reminds me of how I designed maps in the beginning. Do these things on basically every map ever:
-Don't make your maps overly geometric. Meaning don't make everything a perfect grid with a bunch of rectangles and everything in alignment and symmetric. Let's go back and look at two of the previous examples...

These two illustrate the point better than the other two. Look at the shape of the floor plans. It's not very rectangular or symmetric, is it?
-Include a bazillion details. Seriously, one table? Think about including art on the walls, multiple plants, rugs, multiple NPC's, lighting / shadow effects possibly, maybe a cat or dog, put a thing or multiple things on the table like books, additional chairs that nobody is sitting in (don't necessarily arrange them perfectly symmetrically, remember?), statues, other furniture, a clock, random cracks in the walls, random pots, etc.. In bedrooms, you can have dressers, lamps, a foot stool, a pair of slippers, dirty clothes on the floor, a teddy bear, art, plants, a night stand, etc.
-Pick your floor plan and dimensions a little more strategically. What 2-story house do you know of with a giant, empty hallway on the second floor? If you picked your dimensions better, and put the bedrooms in a bit more of an L-shape, the empty hallway space could be much smaller.
-Study good maps and look for the things that they do that you don't.
-Youtube mapping tutorials. You can search something like RPGMaker mapping tutorial or RMVX mapping tutorial or w/e.

Take those tips and apply them to the extreme. Don't just make a slight little tiny improvement in your mapping. Your maps from now on should look nothing like the old maps.

think about the time constraints of performing fucking feng shui on your tile editor.

I laughed.

Agreed, keep it simple and practical and perhaps even finish your game!
I find those overly detailed and heavily parallaxed maps using the RTP (XP and VX are the worst) quite ugly. :X
