Further to a few comments – here is an analysis of what I did this morning.
I don’t have time to write a detailed description but hopefully these notes make sense – please ask questions… (I suppose some people want more details about the eyeline???)
in summary – always establish the main proportions of the building and the space between you and the building (if you are draw that) BEFORE you get distracted by details. Then work within this guidelines. If you make a mistake either- reinstate or just run with it (most people will not know it is slightly wrong…but you have learnt from it)
