A couple of drawings...
Each of these drawings I did over 3 days, for a couple hours each evening. The lighting changed depending on the hour, you can see this most clearly in the top drawing.
I've been working on a couple on linocuts recently. They're not too big, maybe around A3 size, but kind of as test plates for something much larger once I get the hang of things. I've noticed a big difference in the style of image depending on if I draw from a photograph (in the case of Jess, above) or largely from memory (the old man pic).

Ai Weiwei exhibited Sunflower Seeds as part of the Unilever Series in the Turbine Hall of Tate Modern. Ai deals with the theme of individualism in society, particularly in the context of modern China. I found this work interesting for a number of reasons. Firstly, because it was created by several families in a village in China renowned for its porcelain making. It made me think about skills that have been useful in the past but maybe now are less in demand, or have perhaps been replaced by machinery. Secondly this work was intended to be viewed in two ways, up close or from the Turbine Hall bridge. By the time I saw the exhibition people were no longer allowed to walk on top of the installation due to health concerns about the porcelain dust. I thought that was pretty interesting... the intention to have the public interact with the artwork, but to be censored in the end by safety regulations.

Garry Fabian Miller, 'Breathing in the Beech Wood, Homeland, Dartmoor, Twenty-four Days of Sunlight, May 2004', 2004A print made using direct positive colour paper. This paper was originally introduced in 1963 for printing colour transparencies or negatives. It is coated with at least three layers of emulsion, each of which is sensitised to one of the three primary colours. Each layer also contains a dye related to that colour. During development of the image, any unexposed dyes are bleached out (hence 'dye destruction'). The remaining dyes form a full-colour image.
