Saphira was sprawled her full, sinuous length

[suprunp]

He knew that Saphira was sprawled her full, sinuous length on the ground next to him, though he could not see her.
(C. Paolini; Inheritance)
Saphira is invisible now.

Why not: "Saphira's full, sinuous length was sprawled" or "Saphira has sprawled her full, sinuous length"?

Thanks.

They're both OK. In the original 'her full length' is an adverbial - and it's OK too.

Thank you, BobK.

I've got one small additional question.

Considering 'full length' an adverb what is the reason for putting in 'her' before it?

'She was flying high' - can I say then by analogy with the original sentence "She was flying her high".

Thanks.

They're both OK. In the original 'her full length' is an adverbial - and it's OK too.

That works for me only with a comma after 'sprawled'.
