First, might want to report one of your threads to a mod so it can be deleted. No reason to have two going at the same time on the same board on the same subject. Just gets confusing to members responding to help.
As far as the wood, I can't really see what it looks like on my monitor here so it's impossible to say what to do.
Plant-wise you may have some tall growing plants pretty close to the front that you'll want to move later anyway.
I'd say you need to plant more of the same type of plant in groups rater than scattered. Again, hard for me to tell exactly what you have in there from here.
