I have chosen this technique in constructing my artworks.
"Micrography (from Greek, literally small-writing – "Μικρογραφία"), also called microcalligraphy, is a Jewish form of calligrams developed in the 9th century, with parallels in Christianity and Islam, utilizing minute Hebrew letters to form representational, geometric and abstract designs. Colored micrography is especially distinctive because these rare artworks are customarily rendered in black and white."
I may not attempt this style when doing my conceptual piece, where I show homage to the person without actually including them in the artwork (I will probably do the conceptual on Banksy seeing as I do not know what he looks like).
Anyway, this is what micrography looks like.
