as you can see I darkened the one spot on the rocks. You can add a few small ones if you will. I also did the whole of the bottom diagnol .. it now looks right .. I wouldn't worry too much about color. Get the values first and any color will work. Oh I forgot .. you missed an arm of the rocks which balances the ground to the water and horizontal line.
Gotta go now I got a hockey game to watch ... good luck.
