I think im pretty much done with the first (or second, cause the first world is very little) overworld. here it is: And don´t forgett to check my profile. U will see all my userbars there. All of them are true. Userbars never lie.
If it were a fortress, castle music would really fit well because it has this sort of fluid tone in it, but still being in an enclosed building, like that.
It it were a sunken ship, ghost music would really fit well because of the eerie conditions.
If the water was blue, the normal water music would really fit well.
But I can't really decide what would fit here.
I think the normal water music would fit the most.

If you want my input on it, I think the palettes should be dimmed just a tiny bit in the foreground, and quite a lot more in the background - the background seems to stand out a little too much, and the slightly darker palette will make it seem even more like it's really underwater. Maybe give the ground a slight bluish tint as well for a more underwater feel, but it doesn't exactly need it.
Also, yes - the Ghost House theme would fit such a dark, spacious level more than any other song on the SMW soundtrack.
The overworld definitely looks better now, but I still think you should flesh out the edges still because it does seem rather square, and though you added detail to the right island, it seems too much like the left one and it's like they'd be part of the same world. Instead of scattering things evenly, try to clump some things closer together in some spots, and have them spread out far apart in others.
Think about what levels you want to put there, and make the overworld details reflect what's inside the levels. :3 Don't be afraid to make more trees closer together - densely packed trees in one area can make a good spot to put in a forest level without having the whole world be forest-based. You can make a mountain with the SMW land or a marsh using the swampy tiles that are around the entrance to the Valley of Bowser. You can change around the palettes a bit and put patches of sand on that big island for desert spots as well, but be careful so you don't mess anything up when editing the palettes. Try to make it seem different from the left island in more ways, though, since I'm sure you don't want to have so many levels with the same theme.
If I'd make a recommendation of hacks to look at for inspiration, take a look at Eggs of Saear - it has an excellent overworld with seasonal themes and it's put together with great care. RamzaNeko also has a nice overworld, and it's a good example of a correctly-executed RPG overworld, if that's something you want to try.
Keep up the good work - I like how you're always improving over time and keep an open mind for suggestions.
Just look above you... If it's something that can be stopped, then just try to stop it!
