Leila Forouhar: Pop and classical singer with her husband

Focus on moving air from your chest while singing. You should feel pressure in your chest, as if you voice is coming from your pec muscles, instead of your head or neck. When you sing in your "head voice," you can feel your voice up in your throat and head, as if there was a little vibration there. Work on "moving" this vibration around, playing with your voice until you feel it in your chest. This is the feeling you want when singing.
