I like Mach's virt. If this was my tree. This is what I might do. Since the design is going to change, I would remove all the wire and raffia and let the tree grow untouched for the next year. A side note, if you are going to use any of the branches for jins, keeping them wired down for the next year, should be enough so that when you jin them, they should hold the shape. However, I don't think they are going to be a major part of the design, so my initial advice of removing all wire and raffia and letting the tree grow freely is probably the best thing.
Next year, you can remove those branches. However leave all the foliage on the the tree and main trunk you will be using. You can wire everything that needs to be wired at that point. However, I think it might be best to just cut off all the branches that you do not need next year. Then let the tree grow untouched for 1 more year. After that, you can wire and style a strong, full tree. It will make for better health and a better chance of survival.
I realize that waiting 2 years before you can style this seems like a bit much. I mean, we have something and we want to work on it. This is what makes bonsai so different and sometimes frustrating. It's not like you buying a canvas and then someone tells you. Ok, in 2 years, you can start painting on it.
