Looks like a good start.
What are you using for post processing? There are probably things you could do to pull up the shadows and add a bit of color and detail in the rocks on the side.
A better step when you took the shot would have been to use an ND filter instead of stopping down to F22... I'm guessing you were trying for a long exposure to smooth out the water a bit, but F22 loses a lot of detail to diffraction. At 32mm you could have had plenty of depth of field at F11, or so, and not lost much to diffraction.
