I see, I guess it's similar as with 2D tilemaps, good tilesets require a lot of work but then it's worth the effort.
On another note, for reasons I don't remember, I sent you a email to team@mightyandpowerful.games instead of commenting that here. I could comment here but to not confuse you, I prefer to notify of that mail, it would be weird if I copy and paste it here and then you find the email later
