Technical problems (more of a diary entry than anything else)

Working on a painting called 'Mary The Queen and The Sower Of Seeds'. First of all I am wondering whether this title is appropriate. I have concerns over the nature of narrative within painting, specifically how we choose to use this device and how it can best be exploited in the framework of a painting, and as such, is this title suggesting too explicitly the role of narrative within the work, causing viewers to ignore other subtler aspects? I am thinking particularly about the inclusion of evidence for psychoanalytic learning, trusting not necessarily in a chronological story-telling, but more in accurate characterisation and symbolic reference to suggest, not specific narrative, but an emotional space which hints at a story yet allows space for the viewers personal interaction. Although I do like the Folky Englishness of the title and this is a quality I am trying to find and refine in my work. This includes being more specific with colours and finding a certain personal awkwardness which is so often apparent in the best of 20th century british art (I'm thinking here about Michael Andrews, early Lucien Freud, David Bomberg and Francis Bacon).
In 'Mary.....' a wicker chair is proving a problem. It needs to reflect a colouristic relationship with the shadow above the window and the harpists shoes, this means that its colour needs to be changed from brown to red and the way that each colour reacts to reflection and shine is different. How then, do I show its material characteristics? What colours do I use and where? Using Neo Rauch's 'Reflex' as an aid, in this painting there are two divers wearing red wetsuits which have a similar cheap plastic quality to the chair. The application is essentially simple with the tonal separation the key. clearly defined dark cool red and and high pitched cool red. There is then flecks of warm red often coupled with the high pitched cool. In some areas there appears a blue/purple which exists in the region of a mid-tone yet is used sparingly to suggest reflection.
the majority of this should be painted wet in wet to allow a slight mixing between the colours to create the effect of light.
