I want to mod the Rom lowlands 1 tile - the green tile with the treelines - to look like a patch of "drained" swampland. If you check maps of Belarus, much of the land is cut with drainage ditches as the land is marsh in its natural state.

I have no problem taking some of the trees off the tile. However, my attempts to draw ditches looks awful. Exactly like some idiot drew fake-looking, little brown lines all over an otherwise nice tile.

Any art school types out there who can give me some hints???
