Rick welcome to PB. The cliff is a great place for concentrating fish. It appears to be at a good depth 3ft to 10ft +- . You might want to add a vertical brush pile or 2 out from the cliff about 6-8 ft ( a gap between the cliff and brush pile of 6-8 ft). A log or tree that the runs out from the top of the cliff and extends over deep water is also good.

I assume you are not concerned that the area might leak. Sunil's points are good ones also.
