The Secret app — the most meaningful and authentic travel guide created by doers and creators
I am pleased to become one of the doers/creators of The Secret App, which is composed of amazing people curating nice places in cities where they are based in.
Drawing the sky view of London in Horizon 22 again
There are a lot of viewing platforms in London, and some of them are free. Of them my favourite is Horizon 22 which is now the highest in the city. I made the second visit and sketched the same view again.

My sketches of Crystal Palace Subway
I have two related sketches now. One is the imaginative cross-section showing the whole picture of the subway. Another one was done during my second visit as the session was purposed for photography and sketching.
