Post subject:  Overhang shading question
So i've tried work on shading the wing propellers of the Olympic class liners and this is my first attempt:

This is the method i use to shade that part of the drawing.

I used this same strategy on the overhang of the A deck promenade too.

Now I know there is a guide to overhang shading but I'm not sure if I'm doing it right or how to shade that particular shape. One of my concerns is a matter regarding the depth of the shadow so that the wing propellers don't give of the impression or either being too far extended or too close to the hull.

I don't think the guide instructed the shading of a structure of that nature.

second concern i have is if i need to add the shadow of the actual propellers as well.

This is the best that i could do and I'm sure it's wrong because i used the 45 degree shading rule The shadow follows the assumption that the light source is angled at 45 degrees,

not to mention that's how it's cast in many photo's i've seen of Olympic's propellers.

The actual overhang shadow cast by the wing propellers is straight down and the propeller blades cast a seperate shadow against the hull,

Is there any sort of rule that i need to follow? because I'm sure that this is nor how they would have casted such a shadow in real life.

If anyone has any idea on how it should properly be done, please come forward to help. just be sure to provide visual examples since I can better comprehend any advice in that format.

something that reflects it's irl shading as well as staying consistent with the shading of the rest of the hull.

you can use that way of doing shading, but move the shades a little more aft, since the light source aren't directly from above, but from above-front

question here is how far aft and what angle is the light suppose to be casting such shadows from?

Another problem i have is what the propeller's shadow would look like as the blades are twisted.

that is something you decide for your self.... I usually use 45 degree

i would like to see some examples of your shading.

I have also seen some unfinished renders of 35 models of Titanic that show similar shading under the wing propeller:
