Dilapidation - pencil drawing of an old barn

Dilapidation is the title of this drawing. Shading - the tonal value denotes the degree to which the object is in shade.

There are many pencil marks that can be used to indicate shade/value, the simplest one is a pencil rubbed lightly over the surface. You can also use hatched lines / / / / / / / and cross-hatching XXXXXXX, all render shade convincingly.

The rain was very useful whilst using an 8B Derwent watercolour pencil! I used this to add the tonal values to all parts - no cross-hatching.
The insert bottom right, is for more detail of the pulley set-up shown centre left of the barn. (This excerpt is taken from the Oils Interactive CD).
