In my opinion this is a complex sentence. Complex sentences describe more than one thing or idea and have more than one verb. They are made up of more than one clause : an independent clause[it can stand by itself] and a subordinate clause[ which cannot stand by itself].
Let`s take your example:
"Only a little tired of myself" - noun clause [ I am not sure]
.........replied Estella,..-main clause
freeing her arm - subordinate clause[ adverbial clause of manner]
and moving to the...- subordinate clause[adverbial clause of manner]
where she stood ..- subordinate clause of place
If we take "while freeing her arm, and moving ....", then we have 2 subordinate clauses of time.
I`d like to see some experts` advice.
All the best.
