Take a good hard look at these prospects on a boat.
tree tip: dont line them. For conifers, take a bristle brush and "paint" in a kind of triangular pattern to get the pine tree look. for leafy trees, use a solid brush and put a layer with a slight hourglass shape for the trunk, then just scribble a bushy shape on top. if you have a leaf brush, that helps add texture as well (i have a custom foliage brush i use to make texture easier) in deciduous trees. this can be modified to work with most background foliage/rough details if you need 3
