Hi all,

I'm stuck with this advanced puzzle. I managed to start it in the bottom, but can't move forward with it. Even with trial and error didn't work for me.

Any strategies, next step moves would be helpful. Thanks a lot.

Sorry for the resolution, it's from a paper nonogram magazine. Don't mind the orange helicopter, it's form the other side of the page, so it's not related to this puzzle!
