Could you put green squares everywhere?

It's too tedious to fill in, there's too much unnecessary stuff. And some things could be combined.

I can fill it in for you. It's perfect for doing before bed – monotonous work of painting squares green.
And in general, as Revan said, paint everything you think is unnecessary or that you're too lazy to answer in gray.

I like Alex's version, I was going to suggest it myself.

Alex forgot about the redskins.
