Progress is slowing down mainly due to the fact that all providers of images are poor quality. I'm now using all three to make "patch work quilts" for each tile. I did some sums and on average per "line of scenery" (6 tiles) there are over 140 individual images that I have to hand edit. Some of those individual images can have up to 20 clouds and associated shadows which all have to be sketched around and then "cut out" and replaced with good scenery.
This doesn't include the time spent on making the cultivation.
Realistically I think its going to be the New Year before we see any completion of this mammoth project.
