Hi Daggum, glad you like it! :)
There are two textures for rocks and ships and the same goes for water.
U need to pick, for example, dark water and dark water ship.
Hey, thanks for getting back to me. Everything works fine for the darker texture for rocks, ships and water. For the lighter texture the rocks work fine, but the ship colour of the water is too light. I've tried all the different backgrounds but nothing working. A minor point is the water pixels aren't perfectly aligned when you place any of the ships or rocks onto a body of water, but you only notice this when very close so I'm not bothered by it, but it is an imperfection.
