How does an angle of 90° look in your roses?

These angles overlap petals too regularly. An angle of 90° makes roses look very square. An angle of 120° looks a bit triangular. 

Real roses have what turn angle?

In real roses, successive petals turn at the golden angle (137.5° ) which spaces petals well, with less overlap than for other angles.
