Here are the rough mock-ups for the layout,

the first layout is for the intro page for every topic, spreaded across 2 facing pages. On the right hand side, there are 4 squares where 1 square stands out from the others, which will be represented by a thumbnail, showing the topic for this particular section. * the tree illustration is just there for a test

the second and third layout will be the pages showing our artworks.
2nd - the initial idea at first, showing linework then final colour piece
3rd - jl's idea, of showing a brainstorming mindmap of thumbnails, how we progress to the final with colour tests, then the final piece stretched across the page on the right

please give any comments on ways improving on them
and please give useful comments
