I had a 1,000 piece puzzle when I was younger with EXACTLY this scene! That tree hasnt grown in about 20 years. Nice shot but PP let you down a little. Blues look too oversaturated, some chromatic aberration top left corner in the snow. The shadows are a bit too dark to see any detail in them. Still good though!
If this is where I think it is than that lake truly is that turquoise shade of blue. Beautiful scene and great colors. A good shot but I think the composition could be stronger if you were able to compose the shot without the distracting foreground elements of the tree and jutting stone at the bottom half. The tree top and stone interrupts/detracts the vast open blue of the lake. A vast blue lake would complement the vast blue sky.
