First of all, you need to reduce the size of your drawings in order to post them on the blog.
The limit is 400 by 300 pix, however there are ways around it, as you will find here.
Your sections lack contrast. I would suggest that you fill the cut elements with a darker colour (or use a denser pattern).
VERY IMPORTANT: if you chose a pattern to represent the material concrete, you should still have a different way of representing it when it is cut through. The clearest is generally to fill.
Also do not forget that a section presents elements that are cut, as well as whatever can be seen from this cut.
This distance has to be clarified in its expression with a hierarchy in line-weights and tones.
The ground can be one single mass of black or dark grey (no lines unless you want to talk about the different stratum of soil..!). Try to get more information about the site (trees, bushes etc.) in order to express how the project interacts with it better.
Also you should know about the slope and you could extend your section in order to underline this feeling of a flying box. By the way, do you have the book now?
I was suggesting last time that you articulate your entire presentation around the narrative idea. If so, those drawings are also part of it, and should express more about how the house actually is lived/experienced.
Your drawings are missing people and furniture, objects that are relevant to the project (such as the library, the platform in movement etc.)
The paper size is related to this question. If your narrative is an additional document, then yes you can customize it. If you articulate the whole presentation around the narrative, then you should find a way to do so with A0 (it must be possible!).
Generally it is good to understand constraints and try to work within them as they actually are stimulator to generate ideas, and not freedom-constraints as commonly believed.
Best of luck - please answer me for a possible meeting tomorrow. I will be in studio from 5 to 6.15pm.
