Yeah I’d also say to start with the Fundamentals, or even start from the Blender Basics, if you have never not only worked with particles or simulations before, but 3D in general. To jump into Blender and 3D without previous knowledge is usually very difficult, it’s a lot of information to digest. You can follow a tutorial of what buttons to push and you may get things working, but problems will undoubtedly arise and if you don’t really understand what you are doing, you wont be able to adapt, things will go wrong and you’ll end up very frustrated.
I don’t know if for that picture you posted you have to build the whole room or just the water. But again, my advice would be to build up your knowledge all the way from the start so when you reach the point where you’re modeling and doing simulations, you have total control and know exactly what you are doing and you wont just be button pushing for the sake of it.
