Angle 1

I made SD smaller so that it can be smaller than D. The diameter of SO is 1/3 the diameter of SD, X. 

Angle 2

SD was bigger than the D’s diameter, hence I made D bigger which is diameter Y and SD’s diameter shorter such that it is 2/3 of Y.

Side view

The cone is placed at 1/3 of D’s height, Z and Ms Cheryl suggested that the cone should be placed at the side of the cylinder instead. If the tip of the cone is placed directly at the bottom of the cylinder, the cone will lose it’s sharpness and will make the model less interesting.

Front View

This model was not good at all as the 3 shapes were too similar in size, hence I made the D extremely huge, indicated as diameter X, and made SD 2/3 of X. I shortened SO, such that it is 2/3 the height of SD, Y.  

Angle 2

Shifting D up such that the center is 1/3 of the height of SD, indicated as B.

Angle 1

The SO is already 1/3 of D’s diameter Y, but in order to differentiate it even better from the SD, I had to make SO much smaller, like a marble size.

Top view

The position of SD is placed at 1/3 of the height of D, X. The SD was too long hence I shortened it such that it is approximately 2/3 of the height of the cone.

I will be working more on this model as in has a more interesting shape as well as less things to modify. Ms Cheryl suggested to change the arrangement of the model as shown in bottom right of the sketch analysis.
