Final proofing of baguettes

I recently when to baking school to learn baguettes. My family just love baguettes such that I must have every morning. I don't think I have problem with obtaining window frame. My main problem is proofing. I do baguettes again today. I do the finger poking test but still the final result of the baguettes is still not round. I am not sure if the baguettes is underproof. Like I says I do the finger poking. The dough stick to my fingers when I do the poking. I proof for abt 1.5 hours. When I was about to bake just now, the dough Bounce back slowly. If the dough did not bounce back, I guess it's over proof. I try so hard on this. Can anybody help pls. I am trying very hard to do baguettes for breakfast. This is my 4th try. Can somebody help me pls. 

Thnx
