I thought I had it (the Interview)

[tectak]

Splendid lines envisaged, the pieces fit. 
Then like DNA they twist a double helix. 
A haberdashery with this and that to see, 
but noting to fix the bits, they no longer fit. 

The lines billow, then fall miscellaneously. 
The shapes once so familial now form mishaps, 
each unhinged curve a trip or trap. 
Nervous-endings spark then end continuously. 

A dazzled gazelle puffs its fur and growls, 
the lions lick the lips and prowl. 
Their on to me! 
I thought I had it. 

Hi,
before the crits have a great time with this could I ask you to check out your word play. Start with "familial" then jump to "their". These are very basic points.
Best,
tectak
