Believe it or not these lovely cat portraits are not photographs – they were all drawn using a single pencil. Paul Lung, a Hong Kong based graphic designer doesn’t even use eraser – all he needs is a 0.5 mm technical pencil, A2 paper and some time..Well, about 60 hours..

The only problem is that people often don’t believe his art works are not photographs. He even has to make videos of his work process to prove his extraordinary skills.
