Hi Northy! Thanks for your chalenlge. I will start thinking. For you - hm... looking at your pictures, I see a lot of great urban landscapes and architectural shots. What I want to challenge you to is slightly different, the opposite side of the sleek and man-made city - I want you to take a spin on a theme "Urban wildlife". Let me know if this won't work and I can come up with something else.
It's always tricky to get one that works and this is great!
