From an aesthetics perspective, I would have it angled down so it creates an imaginary line up to the nose of the saddle. I would also have the seat post out at a length that is approximately equal to the head tube length. Finally the bars would follow the line of the stem before curling off into the drop.

It's a bicycle, not an artistic composition. The saddle and handlebar position are determined by the morphology of the rider, not your arbitrary aesthetic whim.
