watercolour illustration  

Here we have samples of a 'technical' style watercolour illustration showing construction lines & over draw which were often used to illustrate a 'concept' or 'work in progress' of a product.

All samples shown here were first sketched up and then transferred to watercolour board. A colour wash was built up & pencil line used to define detail.
