Metallic assessment item (Proposal)

Thought i would try and get some feed back before the summer holidays on the metallic assessment piece which in my module is Chapter 10 but really its Chapter 14! An 'item' of my choice mainly of metallic materials. I have in my possession a collection of umbrella bits that have never been used and i have always wanted to use them for something so this was my first choice when approaching this proposal. Initially i looked at umbrellas and 'dead' or broken umbrellas.
looking at umbrellas it appeared to me that the ribs are very much like bird wing skeletons and Tom Waits sang of 'broken umbrellas like dead birds'.
so i started looking at dead birds/ wings etc.
as part of my face study i drew numerous overlapping faces and then filled in the voids which i really liked and hoped to use at some point. after seeing Sian at Urchfont i realised how much these shapes echoed the bird wing shapes.
i then started playing around with these shapes, drawing various ideas.
image 6 shows some of the metal pieces and card cut outs of the face shapes.
thought i ought to mock up some shapes. 7 with the 'wings' closed.
8 with some of the 'wings' open like 'dead' umbrellas. the wing on the right is jointed which i might explore further.
i then thought about a book i was reading, Paul Auster's 'New York Trilogy' where the language of words was explored, citing an umbrella and whether it can still be called an umbrella once it is broken and can no longer function (sorry if this is too deep)! 'it has changed into something else'. i then started thinking of how umbrellas are stored and i usually hang mine (which is almost broken) on a door handle. then thinking of dead birds, i would like to make a 'brace of umbrella birds'. i intend to make the 'wings' from copper sheet, cut and oxidised black. i want to also use very fine copper mesh which pleats and crinkles like umbrella lining. tape ties would have relevant phrases embroidered on them and they would be hung in some way. i still need to work out exactly how and where to include the mesh which might have a degraded appearance. what do you think?
