I love the miniature plants that grow up in the alpine like these.
these are all a bit greeny-bluey, and you could fix that by changing your white balance (or colour balance in post production)
#1 I would crop a little bit off the bottom
I like this shot the best, and I like how you've included the distant background. Also, it has the best lighting.
#3 Most of the left side of this shot is out of focus, and it throws things a bit off balance for me.
#4 I like the lichen in this shot, it looks so alien.
nice work, I like how you took all of these with a low perspective instead of shooting them from a higher, more comfortable working angle.
