What specifically don't you like about each map? The first one is a skill shop, each character standing at a desk offers a specific school of skills. They are all in the same shop because it is set underground and there is only so much room for everything. The second is the second town set in a small rocky valley. The third is just the bottom part of a cave where you fight the elemental earth king. 4th is a small room to fight a miniboss to open a door in the fire elemental area. 5th is a large open map called a hunting map, where you can hunt monsters for slightly better gold and xp than average and fight minibosses that will come back after a timer runs out. 6th is just the top part of a large forest, the gravestone thingy leads to a very large cave which leads to another area. 7th is a probably has the least amount of effort I guess, but it is the elemental plane of darkness (one of three that are like this) and is supposed to look like that. 8th is a very large area called Bloo filled with many caves connecting to many different levels of rocky plateaus. I made a blue fog to go over everything to turn it a haze of blue, the light in the game is cast by the fungi on the walls and ceilings that glow, and in this particular area the fungi makes monsters more docile, so when you are "outside" of caves you are attacked less frequently, but "inside" of caves there is less fungi so you are attacked a lot more. As it takes place underground, I had to alter/change any battleback that has a sky or sunlight coming through a window, etc. The giant green statue is called the oracle and she etches events that happen in the world into her stonework as time passes. Maybe a different color would suit her? Also, the people underground have evolved into all sorts of colored hair/skin over the course of the last 5000 years, many things in their world are not "normal-colored." =)
There is only so much you can do with a 16-bit (or whatever bit it is) game graphic tileset that gives you only so much for options for each set. Feedback is appreciated, thanks =)
