You must just have an incredible natural eye for a good subject—and I think the rapid taking of the shots must add something to that, because I always feel your photos are full of life and colour (yes, I see the irony of saying that about B&W pics, lol).
I also love these snippets of information about Kenyan/Nairobi culture. Are those images actually painted on the buses? Or are they like wraps, stuck on?
