The colors look amazing, that was the first thing that I was drawn to. I immediatly wanted to full view, and then my 'oh wow' went to an 'oh no' when I saw those fishing lines. They're quite distracting from the entire serene scene, but if I try to think those away it's indeed the 'oh wow'.
The reflections look nice. Didn't know Russia had these kind of landscapes
Tranquility indeed! I like these scene, it's peaceful, and gives room for thought. I do notice there is a little bit too much saturation, so I would suggest toning that down slightly and I would suggest changing the crop to better the composition. A very good rule for photography is 1/3, preventing to have anything in exactly the middle, or close to it. With this, I would suggest losing a bit of the bottom, but you could also choose to focus on the fishing lines, and crop a part of the top. Either way, I feel the photo would benefit.
