This is "London Fashion Week 2009" by Illustrator Rob Ryan. (It's not very clear from this picture but the image is actually a photograph of a very intricate, paper cut out design!)
Answering the set questions:
Does it represent a space or a non-space?
The image represents London- 'tower bridge' is a main part of the image and there are even tiny london underground logos around the border.
Is it fixed within a particular time?
It is advertising 'fashion week' in London in 2009.
Does it seem real or unreal?
There are definately 'real' aspects to it- it is obviously a person sitting on tower bridge but it's not a 'real' image- tower bridge is suspended in mid-air and the lady is giant! It is also lacking the colour of real life.
Does it feel familiar or unfamiliar?
The image of tower bridge and the underground logo are both fairly familiar.
Does it feel natural or unnatural?
Pretty unnatural- I don't know many giants....
Does it feel positive or negative?
Um... I don't think that if, in real life a giant woman did actually sit on top of tower bridge that it would be received in a particularly positive manner as the bridge would most probably be broken! However... in this context I think that it's fairly positive- especially if you like fashion... if you don't like fashion then perhaps it's not so positive. Taking the positive negative thing further- the whole image is in only 2 colours- black and white, the black here being positive. Also it is a cut out of which we can only see the positive here as the negative has been removed....
