Walaikum assalaam :) Accidentally stumbled upon your profile and read this message, so excuse me for this comment ;)
I don't practice the niqaab but my sister does and she finds it amazing and beautiful. She finds eternal joy in the fact that she can avoid all the stares and creepy looks of the non mahram men outside home. If you've decided on wearing it, then I think it's a great choice. May Allah SWT bless you and help you stay steadfast on the Right Path :)
