What are the green things on the grass? They look like bushes or something but I can't tell.
Tall grass. They kinda look like vines to me. I'm not quite happy with them. I might do something later.
Overall though, everything looks pretty good. There's some quality about them that makes them look... I don't know, more charming to me than the 2k3 RTP, but I can't really define it.
Hrm, it could be the high contrast and how more iconic things are.
"Iconic" how I enlarged things like the spires on the mountain or the leaves when normally at this high up on a world map you wouldn't actually see them like this. However, I think it fits better when you have classic character sprites and the like since they're deformed on the screen.
Your mind puts it all back together again and you accept it as normal, but the effect is kind of lost when you do world maps that are more like satellite images mixed with typical jRPG sprites.
I feel the contrast and strong colors are important too, it makes it look a tad more earlier 90s than the amazing pixel art you saw near the end of the SNES's lifespan.
I don't have the skill to do something like that in the short time I have, so I went for something simpler I'd have more fun doing.
