Detail in Man-made Forms

This drawing took roughly 1hour to draw and Pencil was used to get the fine detail needed as well as the shading required.

This image is quite complex to look at and very hard to tell what it is unless you really concentrate, the left hand side of the image leads to the right side of the inside of a train, the valves and cogs are not very detailed yet give the impression of cogs and therefore work in this image. Most of the detail is on the shading of the cogs on the left hand side showing how the light is stopped by the large metal structures.
