Nice maps. The textures are good, and it's a clear layout for a dungeon. The part that throws me off is the trees. The texture on the southern one doesn't seem to fit with the shape of the outine. The compass and logo seem a bit basic for the nice textures of the rest of the piece too.
Is this to be used with VTTs? Is that the reason there's no grid? Looking forward to seeing the next installments in the series!
