I could give you the brushes, but they're available online. I would recommend getting a brush set, finding a reference, then using those brushes to capture what you see in the image. Do a lot of these. This will help build a memory for using the brush to duplicate the effect and build your visual library for producing your own landscapes.
Wow! This is really amazing. I love the way you did a lot of details and at the same time it seems simple in the good way. The composition is clear and lightened and the water is just beautiful! (I don't like drawing water it's something really hard and you did it great). I very like it!
