Mechanical/analytical line

I think I was able to demonstrate exactly what I wanted to in this drawing. It is a very straightforward (much like my thinking sometimes) representation of the light bulb. The only problem I can notice is that there is no difference in the texture of the lines. They all have the same weight and composition, so there doesn't seem to be a demonstration of growth from what we've been talking about in the lectures.

I leave you, the critic, to decide if this is an accurate analysis.
