Trista Theme but no featured post

I have just started using a new theme “Trista” and it is supposed to allow me to have a featured post or posts with one of the last entries or latest entries but I can’t seee it. I think it’s supposed to be a banner but I still don’t see it.

My blog is up at https://charlesblog.site50.net/ Take a look and see and help me out. Please, please, please! Thanks much!
