My suggestion was actually intended more along these lines:
Pick one of the light areas (the right one, whichever you think this would work best on). Brighten and enhance it. "bring it out" however you see fit.
All the other light areas, de-enhance them, push them back, make them subordinate.
Do the same with the dark areas. Your primary dark are and your primary light area will dominate, and should be positioned carefully relative to one another, and to the main spine of the picture, that branch. Now we have some things to look at, some main things to start with, and then we can wander out from there to take it all in.
