Hi there Kimicat, welcome to the mapping world of hbgames
There's a whole slew of mapping threads here - there's mine as well, of course, but I'll warn you that my personal mapping preferences have changed. But more on that later.
I'll just go in order of maps, if you don't mind.
1: There's nothing per se
bad about this map, but it's not a terribly interesting one, and it's a bit too random (I think) for being a man-made area. Did you ask yourself beforehand, "What is this tile? How can it be used?" In the street portion you've got a lot of stools just scattered randomly about, and it doesn't quite make sense. The bigger issue I'm seeing, though, is the contrast between the street and the grass. The way you've done it, it looks like it's carpet going to tile. There are two ways around this, one 100% default and one 98% default (so depending on how much you're willing to edit): 1) Use the street autotile and/or the section of tiles in the tileset. It's got raised ridges around it, so it stands out from the grass. 2) Go into the Mountain tileset and take the 8 tiles that make up the outside edge of the grassy plateau. Edit them down slightly and place them into this tileset, and use on Layer 2 to make it look as if the grass is encroaching the street. Which one you choose depends on personal preference as well as the look you're going for. The booths don't make much sense - I can see the street is above them; why would merchants set up in the middle of a field like that?
2:Again, not
bad but I don't understand the map. Why are there lights in the middle of a field? What is your goal in this field? For interests' sake, I suggest adding a bit more variation to the ground (use the lighter grass tile, the long grass tiles, etc), but otherwise I just wonder why it seems to be a developed area in the middle of a soccer field.
3: Is it a...park? I suggest adding a bit more visual interest to the grass, again.
4: I like this one, it's visually appealing, but from a gaming standpoint I wonder about its usefulness. How is your game laid out? Is it in single, small maps or is it just one large connecting map? If it's the former, that row of bushes doesn't do much to keep the player limited to exiting in a small area (which it looks like you were going for).
5: Here's another one with that street to grass issue, but the bigger issue is just that it's empty and boring. Why do you need that huge space in the middle? Who would build that? Is it a town square? It's just too empty. If it *is* a town square, I suggest putting tables or something in the street area.
6: Definitely agree, it's too empty. Maybe make some small grassy areas by the houses for increased visual interest/appeal? It just doesn't seem like the map needs to be that big. I think you can shrink it.
7: Definitely scrap this map. Check out my tutorial for this one - Though, yes, small cramped interiors are not the best for an online game, this is just too huge, and I'll assume that this is how you're making other interiors for your game. The floor doesn't need to fill the whole screen! You can use the Ceiling tile to fill in the space.
