id say #3 or #4. good hardscaping either way!
two pointers to mention. mock-scapes tend look way different prior to adding substrate so try to keep that in mind. also, make sure you wet or spray those rocks before settling on a scape (if you havn't already), quite surprising what a bit of water can do to change the appearance/color/texture of them, i forgot this step in my recent layout and i ended up with an very unwanted white patch on one stone.
