So first I had to find an opera house. A Google image search brings back mostly the one in Sydney, but then I recalled my favorite opera house.
The Opera House on Eureka, Nevada. I'll blog someday about my visit to Eureka. Anyway, I overlaid a grid on it, as I did with the Model T drawing, and did a pencil sketch.
After I had the pencils, I wanted to try my hand at inks. My first effort was with a Copic Sketch 110 - I guess it's an artist's pen, or a pen-brush. I have zero confidence in trying a real ink brush; using the fat end of this tool is a far as I go.
I tried to control the line weight but I am not sure how successful I was. I do like the fluidity of it; good for the impressionistic style I was aiming at.
Then I tried with a straight edge and a fine felt-tip, just to see the difference.
I didn't try to do an architectural rendering; it's still pretty impressionistic, just more geometric.
