Currently working on the ruiny bits for part 2...

Nice map with what is available so far, Remy :)

If you were using a vector style it really wouldn't matter what size you printed it, other than it being necessary to consider the Level of Detail. A town map printed on A4 would be better drawn to just show just the outlines of the buildings, whereas the same town map printed the size of a wall would look a bit blank if you didn't add all the chimneys, lose tiles and bird's nests. That's Level of Detail, and it's important to get it right for the size of the end product.

A style that makes use of bitmap fills and symbols is limited by the resolution of the fills and symbols, so you have to be careful not to print it so large that the individual pixels of the original artwork start to show. This has nothing to do with the resolution of the print. You can't print a symbol that is 100 x 100px at such an enlarged scale that it is effectively 1000 x 1000 px and expect not to see the enlarged pixels of that tiny symbol as little squares.

The best way to find out is to print a small sample of the map at the desired size and see how the bitmaps hold up.

It's always a question of whether to design a template based on older templates, or to change the design in a way that better suits the style.

In the case of Darklands City it was easier to put the effects on the water generally, with the added bonus that you can run terrain under a river and not have to have a sandy beach the same width all the way around.

But if you prefer to swap things around to suit your map better, that's fine too :)

There's a Color Key sheet effect on the WATER sheet.

If you pick the majenta colour (6), make sure the fill style is Solid, and the active sheet is WATER, you can use the tools on the right to draw the island.

There should perhaps have been an island drawing tool, but I think it got overlooked at the time. I will see if I can make sure it gets included in part 2.
