You have some nice shots there, but some specific comments. If you shot in raw, try to recover some of the highlights on the first one, as I think there could be some more detail there. For the coal tit shot, I would crop on the right to the curving tree trunk and may be crop some of the bottom as well; you could also play around with some crops with the blue tit as well, although I don't think that image is as strong. Other comments would be to be careful of clipping the tops of buildings and try not to crop too tight on the sides, but some of the deliberate tight crops of the statues works well.
My favourites are probably Bridging the Water and the second Eckelrade shot; the use telephoto on Eckelrade, with the simple composition works well.
