I made this this project because I was annoyed how the concrete symbol wasn't like the sand and water symbol. I also slightly changed the spray symbol and dropper symbol. That is it ;) Griffpatch, If you see this, you can copy the concrete, spray, and dropper costumes ;), and you do not need credit.
The concrete costume was rather overhauled. I added a missing square to the spray and an outline to the dropper. Nothing else was changed. These 3 were my pet peeves until now, when I fixed them, as you can plainly see.
