I didn't know there was a second part to the sketchwalk at Toa Payoh. Apparently one sketchwalk does not generate enough content for a book so we had two. Oh yes, we are compiling the sketches for a book.

I've used the stippling effect instead of the usual graphite tone wash. The bottom of the mouth is slightly off.

It's very challenging to draw housing estates. If you're drawing from the ground, you'll be blocked by trees. If not, you'll be presented with boring buildings with countless windows.

I saw some kids playing with a cat.

See how much trees we have? Blocks of flats are behind, each more than 10 floors.

An incident happened today.

My friend Drewscape (man in white) was questioned by the police. He was deemed suspicious for drawing the police post. So they spent an unnecessarily long time asking about his strange hobby. He's clearly an artist if you look at his sketchbook — they did. His drawing pals are all artists. No person sane will draw your sensitive building when it's easier to snap a picture with a camera phone. We may have one of the best education systems in the world, but we don't test for common sense.

So the police invited themselves to our show and tell to see what these strange people are doing. 4 policemen are definitely not enough to control a crowd like this. Especially when the crowd is armed with pens, brushes, watercolour and paper. Some had weapons of mass communication like smart phones and cameras. Once these things get online, it could get viral, like influenza, or a Rick Ashley song. That would be very bad.

By the way, a good portion of the group are students. You know how students are. Young and reckless. Anything can happen. Nothing did. Lucky day.

They are just doing their job. It must be quite boring at the office. We were all told to leave behind our contact information for reasons we were not told, or I might have missed it. We won't be able to comprehend the reasons anyway.

It's a nonissue so we were able to leave happily ever after.

The moral of the story is to be mindful when there are sensitive buildings and people around.
