Thanks for comments!
Actually, I'll post another version of these tiles and some other tile set, for a more cartoony type of game.
Nice...kinda dark.
I might need those later. I'm making Resident Evil 2d and those tiles would fit for later in the lab/sewers.
Glad they might help you. I'm making tons in a style kinda like that. I'm actually stablishing a style for a MGS type of game.
my best suggestion at this point would be to make a floor tile. It will add a lot more readability to the set and also make it more interesting.
Yuppers, I made one but I hated it, so I just put a simple grey floor for the moment. But I actually WILL change it, of course. Not in the next set, though.
The perspective the tiles are at makes it hard to see into the rooms. And the wall grains look unnatural. But it's a start. 
Yup, I changed the grains, it complicated things way too much and didn't look right. As for the perspective, Chrono Trigger works kinda like this. I prefer this than the unrealistic Lttp tiles.
Now, on to the tiles:
First set
This was a start for a cartoony-like tile-set. Obviously, it needs a lot of work.
Second set
These were made before the last set. It follows the same cartoony style, hopefully.
I don't feel like uploading another set, maybe later. Oh and, if someone wants any of these tiles for a game, just PM me and I'll send you the set.
Ohhh, almost forgot, the updated set:
Feel free to comment on these.
