I am too unfamiliar with darkroom work to say anything much, but other than that I like the fact that the bus is so obviously moving with the houses and the protestor being so still (which I like a lot about this composition), I find it a bit flat ... wouldn't harder paper have helped to up the contrasts? (That is what I remember from when my uncle did darkroom work - I was under 10 at the time, mind!, and he used to take either this paper or that, 'soft paper' or 'harder paper' or 'very hard paper' to bring out the contrasts). Tell me. Help me here.
