My mom's look just like yours. She's basically a pro gardener so don't worry, they will show up!
Patience young farmer...they will start popping up soon. :) The plants look wonderful and healthy...before you know it you'll have more tomatoes then expected!!
No idea of gardening.....
See those branches with the big leaves? They're called laterals, and they won't ever bear fruit. You should prune them off, and get a stake and train the plant up, to maximise yield. Expect some by late Spring, I'd say.
