rikyrik, if I mentally rotate the image clockwise, the right side seems bereft of leaves.
Provided that the cause of leaf loss has been identified and corrected, I would start at the top of the main stem and gently scrape the bark to see if there is any green (living) tissue underneath. If there is none, I would repeat the exercise a few inches down at a time until I do find some green. I would then remove the dead portion. I would do the same for the lateral branches and cut away the dead portions.
Bright light and careful watering should induce new growth.

Sorry for the pic I uploaded from my phone, ive done alot of trimming, nearly everthing with no growth was dead im going to move it this week hopfully.
