Requires guessing.

The picture is good and the guessing was easy. :)

Nice design but it's worth giving the puzzle a trial run first to make sure it's logical :)

R8c5 and r18c19 must be tried using contradictions. That's different from guessing. (cf. WikipediaNonogramContradictions) Nevertheless, it leads to multiple solutions in the rectangle r9c20-r11c22. It's a pity.

The first part of Juwel's comment is not accurate, but correct that the ambiguity is three single pixels in R9-11, C20-22.
