This is great landscape piece with good use of watercolor techniques. And the use of a limited color palette, saturation and value gives this painting a good impression especially the use of light which centers on the mill, drawing the viewer to it. The concept gives an impression of a dystopic world given the dark, swampy colors, So even without looking properly at the image, the eyes are already focusing on the mill. From this perspective it's as if the mill is the only remnant of a younger simpler world built into the mountain and then the scene opens up into the side giving more space and not crowding the painting. This is both an effective use of color, perspective and lighting which avoids a claustrophobic effect common in paintings that cram too much. Given more practice, the technique could improve and I think pretty soon, this could become more realistic. Keep up the good work
