Hi justask,
you are using the Studio release, so you can work with layers.
Just call a second time the text module with a différent font and size, and use the effects functions of the text module.
for further effects convert the text layer as image layer (right clic on the layer thumbs)
and try menu Filter/Stylise/Contour3D or any filter to make shadow, gradient of gray, blur, and so on.
