Boogiechile,
It looks really good! I think you’ve done a good job on the rocks, especially the shadow side of the large rock formation that sticks out in the water.
Rocks are hard. One technique I use that you may find useful is block in the overall shadow, mid, and light tones as large simple shapes, then go back in with accents of dark and light to make the crevices, irregularities and planes that pick up the light.
Good job on this one!!
