Both the water and 10-ton trap were made way back in 2005 or 2006. They have several problems: The cell-shading drawing style simply doesn't fit with the modern tilesets. They looked better among the other terrain pieces I made, but I consider even those inferior to the other tilesets. The water has an additional problem with the flowing animation; the waves seem to move back and forth.
And they're horribly to place, they were made when the possible grid sizes were 1, 2, 10, or 25, not 1, 2, 8, 16, with 8 being changable into anything by the user.
There's actually a need for better water, Matt's sawteeth water isn't popular either, except with highly abstract styles.
