I created this map for one of my daughters' D&D games that she DMs for her friends.
It's a pretty simple wooden bridge over a river that flows through a section of woods. I personally think it looks a bit like spring, with some trees growing leaves and a few that haven't started yet. It could also be for a bit of forest with some dead trees.
The gridless map comes in two resolutions, so you can choose one that looks slightly better when zoomed in (140 pixels per inch) or one that is a smaller file size (70 ppi).
