What's missing? A defibrillator.

I'm not an expert, but it seems to me you're combining too many areas of Italy. You can have white wine and butter, or butter, garlic, and olive oil, or tomato and spices, or a cream suace, even slightly tinged with marinara, but I think you have every possible Italian sauce ingredient in there. You probably need to take out something, not add in something.

Get out an Italian cook book and go over the basic sauces. The answer should become obvious. For instance, if you go with a red sauce, you'll need something like basil, oregano, or rosemary.

And salt. You gotta have salt. Completely absent, food tastes dead, add just a touch.
