Hi Madolche, welcome to the 405th. Not to be a buzzkill, but this thread is for costumes that have been completed, not ones in progress; that's what you can make your own build thread for. You can also ask for critiques in your own build thread. As for the question, it really depends on the helmet in question. I would check the other threads here. Really with any question you have, chances are it's already been answered more than a few times, especially in the stickies section. Cheers and happy building!
