how is a b&w sig good?

what does someone need to watch out and what does he need to do for it to come out as a proper bw sig.

I guess the same stuff as when you're making a coloured one, maybe put extra work into contrast, shading and lighting.

You can also go b&w and add just one or two colours in one spot to add focus.
