The next version of FotoSketcher (2.45) will include a new abstract effect (based on shaded triangles) and better brushstroke placement for the Painting 7 effect, which should give an even more painterly look.
I have also detected a bug in the manual brush code which will be corrected.
Here is an example of the new shaded triangle effect (click on the image to see the details):

All the best,
