Soda lid puzzle

I thought this puzzle would be easy because the pictures are divided into smaller squares. I was wrong.

August kept preventing us from working on it (as usual, but more so this time) and it took us around two weeks to get it finished.

Look at that concentration!

I thought we were missing one piece and we started looking on the floor for it but then I realized B had set it on the puzzle. Who does that? Anyway, he got to put the put the last piece in. Maybe that was his plan?

All done. This was a really hard one. Too many shadows.
