Avocet picture pretty good, but being really picky, the farthest bird is in sharper focus than the nearer one. Did you have a small enough aperture to put both birds in sharp focus? If conditions prevented this, an option would have been to wait until only one was in frame.
Dockland scene I'm not so sure about. To my mind it lacks a focal point despite the intention being one of balanced equilibrium. The obvious item is the chimney, but being central, the eye keeps wandering off to other points of interest. For example, the trees in green at lower left or the boat. Then the tower cranes at the extreme left are cut off and lead the eye out of the frame. Finally, the rope in the lower left corner is a bit distracting. So in fact, the picture does not deliver balanced equilibrium.
Sorry if this seems a bit harsh, but your request for opinions took me back to camera club days when competition judges used to say things like that about my pictures.
Two really good pics, could you send me a high res copy of both as I would like to use at least one as a canvass for my office.
Is it just a hobby or are you a photographer? I really like the Liverpool one as it reminds me of Graphic design at school, drawing 3-d perspective drawings using a central point and showing the proportioned angles affecting the scales.
It is often something I would like to take up but my hands are too shaky for Photo's!
