I love the shape of your eyes, so pretty! I would say too that contouring your nose would be the most easy thing to do if you want to define it more. Contouring can be tricky for some, and nose contouring even more. Basically though just put darker shades on the places you want to look like are less forward, and lighter shades on places where you want your nose to bring forward. When placing darker colors to the nose area, also do not forget to blend it upwards into below the front tip of the brow bone and eye crease. I think that gold, copper, and warm shades would really make your eyes pop! Also peach tone reds and nudes would look good on your too! Best luck!
