This was just awful. You need to check your work before submitting. This is just ridiculous.
I hope this can help those who still bother to try and solve this.

Thanks NiftyStrawberry.

Only a few ambiguous squares at the very end. Beautiful design. Thank you for the puzzle!

Mostly logical except for a few of the raindrops (thank you NiftyStrawberry for the tips). Overall nice pic!

I agree with Strigoii, some guessing at the end.

Couldn't get solution accepted. Utter crap.

Thanks for the hints.

Idea is a nice one. the execution terrible. Test it!

Also, R21 C17 and R22 C19.

Almost logical. Thanks.
