Urban Sketching, the Biltmore

Let’s talk architecture
One of the most difficult subjects in drawing is architectural drawings. For one thing, you don’t need to become an architect so you don’t need to know everything. If you stick with the observation through the viewfinder, your eyes will see what a certain angle is. You cannot trust your brain.It will see the slant completely different. When in doubt get a viewfinder.
Another thing that is very helpful is that it is only your perception of something difficult. It is not really. Architectural lines are straight. They can be under a certain angle. Try to find that angle. Negative shapes might help. Also you will get in the flow when it is difficult because you need all your concentration.
