Thumbaniling - Paris

The first city I've decided to illustrate is Paris - and within the city I really wanted to illustrate the Georges Pompidou Centre or the louvre as opposed to the Eiffel Tower or Notre Dame, etc.

Some studies of the Pompidou centre and a couple potential thumbnail ideas. The two strongest ideas I feel are the two top right thumbnails  - the side view captures what I think is the most iconic part of the building: the outside, pipey escalator. I also have considered limited used of colour, or at least which colours will be dominant in the composition.

Consideration of the Louvre by exploring different potential viewpoints. I think that the side view is strong just as with the Pompidou centre - a simple triangle shape for the Louvre being quite nice.
