Do any of U know where I can find some good DD3 symbol?

Right now I'm creating a DD3 map for a Board game I'm creating. The map will be of a sorcerer tower, a Castle and a cave all link to the throne room. First player to get there win.

The problem is that with DD3 default symbol, you don't get many creatures symbols. For the castle , I want to have human guards, priests, wizards and prisoner in it.

For the cave I need a big animal like a bear for the rest I've decide to use the default insect and undead symbols from DD3.

For the tower , it should mostly be magical and normal traps, plus a demon and some golem like monsters.

Free stuff would be welcome, but in the worst case I can buy symbol set if they are good.

Thanks all,
Alu.
