Looking more closely now that it is not on a small phone, that is a perfect size bike for you if the seat is in the right position. A smaller frame is going to necessitate a significant jump (2cm) in seatpost height from seat tube. And then the corresponding stem (Technomic zone)
Maybe get a shorter stem reach, and I agree with everyone here, move the levers around and up until you find a comfortable zone, looks be darned. Neal has a nice rule of thumb I am going to use for quick adjustments...
