This is a very nice and beautiful scene!
The colors are great and look natural.
Plenty of blades, flowers, subtle details and overall very convincing.
Thumbs up...
What you could do better is the overall lightning IMO.
It's to dark and the green colors are totally bleeched out. A lively image results from great and lively colors, many variations inside a color spectrum (like green for gras).
If you are willing to work over, add some rocks and stones this scene can become a true contest winner. I would definitely invest more time here...
Lake Tahoe 12 (Cutout)
Lake Tahoe 13
This is an example what I mean... A clean sunny day with bright colours in the greens and the result is somehow lively and pushing.
But it's a question here. Which effect do you want to achive? A a lively or a more naturally look? Your look is very natural (but leaves a dull impression).
So it's just my 50 cent here...
