there's a point in development where you're in it for the long term. after that point it'd be easier just to start over from scratch. i don't know how far into development you are, but from your screenshots, it looks fairly significant. you might still be ok, but if you'll have to redo a large enough amount of areas, it's better to just scrap what you got and start again, or plow on through.
the different styles between areas have always concerned me. stylistically, some things just don't belong, and i was worried it'd eventually take it's toll on the project. in regards to the battles, you're pitting chibi final fantasy sprites against works of art. middens and off did similar, but kept a similar palette throughout to make differences less jarring. i don't know if that's the problem you're talking about however, but that's what I'm worried about. what do YOU think is wrong with the battle system? if you uploaded a picture of it, it might be easier to tell what's gone wrong and how to fix it. also keep in mind, you can position the characters and enemies sprites anywhere on the field. you don't have to just line them up on one side.
i really don't mean to sound overly critical. I'm a bit of a pessimist. still, what you have shown us so far is great, and I'm looking forward to more of it. i do have high hopes for the game, even if it doesn't sound like it. you are an amazing artist.
my complaint about the bedroom is that it's a bit flat. perhaps add more colorful decorations to it to make it feel more 'lived in', such as pillows or a carpet, or books, clothes, or a lamp.
