I like the Liberated Pixel Cup Farm tileset but it isn't exactly what I require to illustrate some Maize breeding work. I have very slightly modified some of the soil tiles to create a field with aisles/pathways between ranges of rows but it is very flat and straight and not exactly what I want. I need to modify one tile to have the first row closer to the edge on the bottom. I have both horizontal as well as vertical rows and the plants don't really lie up with the rotated row furrows. The row-end tiles have 3/4 of unused space and I am thinking of modifying them by adding more row in the tile so the end has half a pathway. I want to show my field illustrations and tiled maps to the public in a youtube video and then in my Walter Mitty style 2D RPG, but I am wondering how I should attribute amateur modifications the original creators might not want the public to think were the prduct of their work. Should I include some kind of clause after the attribution that says the amateur looking modifications were made by me?
I am using an approximate scale where 1 tile represents 3 square feet. It seems a bit long and if I had a modified aisle tile, I might half that scale so that a row is only 3-5 tiles long (3 row tiles and 2 end pieces with half an aisle each). I want long rectangular ranges, not the squares of Farmville.
