It's very difficult if not impossible to have two different pieces of hardscape (one rock one wood) not compete against each other for your attention (focal point). One has to support the other one. Putting the wood together is good, the the rock is way too big and sits by itself and would only distract from the wood grouping. If you want rock in there also you need to use smaller pieces and place them foreground and midground around the wood grouping so it all works together. Just my opinion from my experience scaping.
So what you're saying is lose the big rock, and put some smaller rocks around the DW. If i still want structure on the left, I need to use wood and small rocks instead of one big rock there? Or, are you saying that if I use wood structure on the left, it needs to be smaller so as not to distract from a single focal point?
