I don't quite follow what you mean here. Is what bonsainut came up with the direction you were going?I would say that once the branches have been set in a more horizontal plane......
A quick virtual that might help you think through the design. I think your choice of the front is correct. You need to get rid of the vertical branch on the right. Once that is done, I think you see the line of the bottom half of the tree, and the challenge comes down to creating a new apex that balances the design.
