Shape looks good. However I would like to note that with you wrapping the entire trunk, you are limiting yourself for new buds to emerge at strategic locations. Unless of course you don't need new buds anywhere else on the trunk.
Also I find two smaller wires wired in parallel works better than one large wire. You have more control when you are bending.
Buds find a way. But yeah they won't grow from under the wire. I guess buds respond to light as well.
