Yeah. So did I, which is even worse.

What with Wyvern wanting Wyverns, and Remy wanting cats, we need a style that is all the pets and monsters.

The scale of symbol is usually conveniently organised within a single style, but where you have mixed styles the comparitive scales between houses and hills (for example) is at your discretion. It's a blend of what is recognisable for what it is, and what looks right to you.

A map symbol doesn't have to be accurately scaled to life. A good example of this is the size of overland mountain symbols, which are many more miles wide than a mountain could be in real life. However, they do need to be that big so people can see that it's a mountain range and not a line of squashed ants.

Nice use of the fishes... es. :)

That's because nothing is as yet set in concrete.
