I am near the end of my course studying and i am doing a floating Island in the sky. i did the base mesh now i am sculpting the rock cliff face. I need some critque and suggestion on this.

Are you using reference? If you're going for a natural looking underside then I think it looks far too man made. Try looking up some rock references, copy them to get yourself started and go from there maybe.
