Hi mate,
Thanks for your kind words. The book's focus is architectural sketching from a plan (or imagination in broader scope). So it is not intended to learn the audience to sketch from reality. By the way, there are some perspective rules that are valid in both sketching from the reality or mind. i.e. when it comes to dividing a line that heads away from the viewer the rules that I have shared here are the same in perspective drawing from the real world or mind...
Will try to share the table of contents.
