Great location, but these two will improve the shot:
Composition perspective - Maybe find a better foreground that leads into the scene?
Technical perspective - Shoot earlier in the morning where light is more pleasing, and chance of mist and fog. Use a Graduated ND to bring down exposure on the mountain top (very important as it's much brighter than the rest of the scene), If not, use HDR but don't overdo it.
Here's my take of Reflection lakes, I like the foggy effect but when it's clear, it's pretty but boring.
I find Tipsoo lake over in Sunrise a better location as I had much better conditions and better foreground every time I was there.
