My first brush! Created for map making. There is a brush that is only the line art, and one that includes a fill. Color adjustment can be made on both. For the brush with a fill, the line color and fill color can be changed independently based on your selected colors.
The original drawing is a raster drawn on a ~950x500 px @ 300 dpi canvas. As such, it's better to use this for small map details versus having it be a focal point of your drawing.
