Yeah...the first one is a bit too busy because of the fencing & stair railings. The other two are a bit too shallow. Add a bit more background & I think I'd like them more.
I like the first one as there is a cetain symmetry to it, the other two are just snapshots. I would like to see the original coloured images, as these do not have enough tonal contrast or tonal range to be good as black and white conversions.
