Reminds me of one of my trees a few years ago. Here's a link to a bit I wrote on its development (actually, it was an email I sent to Jerry about my tree which I brought to his workshop, which he put on his site):

If you have some time, take a look around
Jerry's site--incomparable for ficus info.
If I were you, I'd start thinking about how you want this tree to look in a few years. Then start growing in that direction. There is some nice movement lower on the trunk of your tree, but the rest doesn't harmonize with it. I don't know how large your tree is, but if it is still bendable, put some wire on the trunk and make some pleasing curves around that bend. Don't forget to curve front and back as well as side-to-side.
Once you have the basic trunk shape, select which branches to keep. Allowing some lower branches to stay on will help grow the lower part of the trunk and therefore increase taper, so don't be too quick to cut anything off. Just be sure you know why you want to keep each branch and you'll be alright. Keep the top of the tree cut back more than the lower part, and be sure to keep up on pinching or you'll have branches, especially upper ones, swelling rapidly.
Another option is to chop the trunk back to a side branch which will become a new leader. This will create taper more rapidly. Also, don't be too quick to plop that tree into a small bonsai pot. A shallower pot, but one that is wider (like an oversized bonsai pot), will allow faster growth, lateral extension of roots which encourages basal trunk flare, and also (in my experience) help avoid the "potato roots" bengies are famous for.
Good luck, and please keep us posted!
