Did this 45 minute sketch today using a parker pen and black ink. Gentlemens Walk, Norwich, opposite market. Overcast and about 14c. No interest from public. I think if I use an easel instead of sketching on lap seated, I may get more feed back. I feel it is fairly obvious what I am doing yet people will stand in front of me oblivious to the fact they are blocking my view.

Coloured sketch at home with watercolour. Ink is not waterproof!
