Yes. That was the one.
It can be difficult to manipulate the trunks of a forest that has been put together for a while; much better to have done it beforehand, but that's water over the dam and thought for your next forest.

That said, for all of those middle trees, I would have used wire at least 2 sizes larger, and started it from the roots up. In addition to the top, I would have put some
slight moment (forward, backward, sideways) in the lower trunks, too. I think I'd suggest snipping (NOT unwinding) the current wire and doing it again with the larger wire. Added movement should not be drastic; just get away from the stiff-as-a-pencil look.
Whatever, this should turn into a nice grouping.
