In this session by Frank Ching, we went to the riverside and I drew Steel Bridge. It was a really unique bridge. The middle of lower part of the bridge is movable: A vertical-lift bridge. I saw it went up and a ship went through the beneath and then it went down. After returning it's original position, then a train ran across it. (You can see the train runs in my sketch. )
Mr. Ching's advice to me was to follow the way how the structure was built.(I don't remember the exact phrase but I understand something like that) And to draw the structure, you should draw not only the thing you can see ( superficial details) but also draw hidden part behind. I'm still not so happy with my result since I couldn't capture the lower deck of the bridge. There are some missing pillars backside but thanks to Mr. Ching, I like the upper part.
Then I drew the buildings seen across the river. This glassy building was a tough one. I couldn't figure out what it was exactly like. After drawing these sketches I realized that how great those fellow architects' understanding of structure is and how skillful seemingly easily drawn lines are! I added colors even though it was a Urban Line session. I couldn't resist my desire to make up my deficiency.
