try to recreate the atmosphere of the beauty that you feel on the shore of the lake.
Some things that would spice up a lake picture like yours would be to tighten up the shot (zoom in) and capture some water, some shore line and something of interest, like some babes on a jet ski, some nice architecture or an animal. Use the lines of the beautiful scenery to pull your eye to a point of interest.
A great sunset or sunrise would be nice - and it would also give a nicer light to the photo.
Look throught the forum for some scenic pictures that convey the emotion that you feel and study their composition and lighting.
The PP that the above poster refers to is Post Processing. This is a program like Adobe Photoshop Elements, or one of many others, that will let you crop the picture, adjust the lighting and manipulate the picture in a whole bunch of ways. Post Processing has a learning curve to it, but the control that it gives you over the final picture makes it well worth learning.
