I like your burgundy sweater, you could wear that on its own with a jacket and no dress shirt.
The turtleneck with jacket is proving a popular look this fall.
Your navy suit looks okay, can't comment on fit. I don't even mind the windowpane one.
You do need serious help in the pocket square and tie department. One thing if suggest is to avoid the super shiny stuff.
With the stuff you have I'd err on the conservative side. I wouldn't go wild with colours, focus on time...
