I like your initial ideas, I definitely think that straight piece needs to come off where your number 2 is. What about layering off that branch, maybe where it divides into two trunks a few inches above the zip ties. I wonder if you do that, if the left main branch will have to be cut back too to balance out the energy? Either way, I like it!
What are your thoughts on carving the deadwood, how much are you thinking?
