This looks really nice! So, what do you do for a living? )) maybe it should be icon design))
To my taste row 2 looks best.
Just a few things that caught my eyes:
- I don't agree with the "plus" sign to mean "anywhere". It already has a very strong meaning as "add" or "expand".
This is why I think this icon should be of different color. And maybe asterisk instead of plus would be better?
- The size icon has something in the middle what makes it look like an empty glass;
- I kinda liked round handles of scissors

But this is just me nitpicking)) The icons are great!
