Planning a 5 course meal - I wanted some thoughts from actual chefs

Hey y'all,

Not a chef, just a home cook looking for some advice. I'm planning a 5 course dinner for my friends and I'm looking for some advice. So far I have:

1. Caviar on blini with crème freche
2. Crispy skin pork belly with a caramelized onion jam topper
3. Arugula and spinach salad: Lemon vinaigrette, shaved parm, some kind of tree nut
4. Braised short rib with smoked gouda mashed potatoes
5. Homemade coffee ice cream with a chocolate fortified wine poured over

I'm planning on making the short rib and mashed potatoes the day before and maybe cooking the pork belly and crisping it up day of.

Do y'all think this is a decent line-up? I'm more worried about going from caviar to pork belly as that seems like a jump from more delicate flavours to fatty and textural.

Any thoughts or criticisms would be greatly appreciated!

Edit: thank you all for your help, this is more of a casual 5 course than a sit down! I love all of the advice given so far, y'all are great!!
