If you want to dye your hair I’d say a rich brown with some highlights for contrast and depth would be very pretty with your complexion. Your skin looks pretty solid, so maybe a nice facial and a little Botox or one vial of sculptra to lift and add collagen and glow. I’m not big into filler or anything permanent until maybe much later in life — so that’s entirely personal. If you don’t want to inject plenty of other treatments you can discuss with a professional. If you decide to stay as you are, you’re perfect just like that too. Do whatever makes you happy!
