collage base - montage trace

This is perhaps a bit too still at the moment.  This is the beginning of an axonometric collage drawing I am making in order to plan out the inversions/slippages/indications/etc for my montage passage.  This of course will need to be larger, and I am quite determined for this to be critical.  (I spent Saturday beginning an axo of Friedrichstrasse Berlin)  I also need to ensure that this passage collage stays in line with my objective,,
