I like the more natural styles and I am a great fan of penjing. The problem here with your tree is that is looking a bit top-heavy and that will get worse as it grows. If it were mine I would prune off the second heavy branch and then let it grow for a while until it 'suggests' a style.
It doesn't really have a style yet. You gave us the same picture 4 times, so there's no way to advise on further development. Both of those "trunks" are unsightly from this view. The left hand trunk is VERY top heavy. The right hand trunk is too straight. neither has much taper.
This plant should not be in a bonsai pot. It needs to grow into itself.
Love the virt, that looks like a great plan, and interestingly enough it is the twin to a tree I used to climb in as a kid. I actually built a a fort in the middle section out of several pieces of crate wood and some tin, which lasted for about two weeks and blew down in a wind with me in it. The crook that I built it in took eight boards nailed into the tree to get up to from the lower branch and my cousin lost his front teeth when one of the boards popped out on his way up and he fell face first onto the lower branch.
