Well I have a rough 32x64 base icon made for my game and I was curious if i should adjust the size of my turf and Skill icons also I wondered what a good size would be for these
You can change the base tiles size with world.icon_size. From the ref:
"This is the tile size that will be used as a default for icons in the world. It can be set to a single number that represents both the width and height, or you can use a format like "[width]x[height]" (such as "16x48") to specify width and height separately. "

You can override the default size with specific icons. If your default sprite us 32x64, I would recommend sticking with 32x32 as your basic tile size for turfs. I would also recommend Forum_account's Pixel Movement lib here: http://www.byond.com/developer/Forum_account/PixelMovement .
