You've constructed this as a kind of chain, rather than as a hinged
bracelet. Jump rings allow movement in 3 axes, you want to restrict
the movement to 1 axis. Also, that the rings project below the bottom
of the tubes will force them to tip over, as the tubes cannot rest
directly on the wrist.
I've uploaded a drawing of the type of hinge I'd use to construct the
bracelet I suspect you want. Keep in mind, it's quite a lot more
labor than just soldering on jump rings, but it's how a well made
bracelet would be constructed. Note that you'll have to file relief
angles into the tubes below the axis of the hinge wire, to allow for
the hinges to move.
Also, if you do make a hinged bracelet it deserves a nicer catch
than the lobster clasp you used. A proper box clasp built into the
tubes would be best.
