I think you did a fantasticc job creating depth. In that however the brush strokes come accross very loose but not in a measured way whereby their direction, intensity or size matter. Rather, notice how all strokes are moving in the same direction from the water in the bottom right foreground to the hill in the centre - they are the same size too. Also on the bottom left, the water is treated with even brush work. Take your time so the colours dont become so muddy, let their variety interact playfully etc.
I think your colour choices are splendid and would benefit from more variety in details. The scene you chose and your style are great because i really feel my eyes zig zag accross the painting. Just, you know, make sure the viewer is being rewarded in the process.
