I dont normally offer much critique or opinion other than 'nice shot' or 'its not for me', i dont feel that im technically competant enough to critique other peoples work, but as Steve wants peoples honest appraisals, here are my thoughts, they are only my opinions mind!
#1
Very pictureque setting, with good symetry. If you look through the arches, you can see the light on in the courtyards on the other side, suggesting that they are bathed in light while the walls this side are in shadow, i like that, though nature could have been kinder by giving more blue sky and less grey. The refelction on the water is good too, leads you into the shot well without distracting from the building, which is obviously the focal point of the shot. Could be my monitor at work, but the snow looks a tad blue.

first thing that grabs me is the blue sky, its very blue, which i like, poloriser used? Unfortunately im not that keen on the rest of the image, i can see the netting over the buidling, but ive got to look very closely to see it on the building itself, i assume its to stop pidgeons pooping all over germanys finest? I cant find a focal point though, but then i dont get architecture, so im not really sure what im looking at!

For me its the pick of the shots, its simple and highly effective, the colours and textures are really good, a well spotted shot, i would have seen some stairs, as i said before, its that vision that makes the difference.

natural framing from the trees, with the gold top of the dome placed on the third, but im not really sure how i feel about the rest, im looking at it, and its nicely composed, but im not really 'getting' it again, the detail of the architecture is very good, something carefully looking at the picture you notice, i didnt see it first time round. Looking at this shot on its own you miss the fact that the portion in the shot is snow covered, but the other side has melted snow, you can see that from the next shot..

As mentioned, the snow is blue instead of white, again i think architectural photography and me dont get on, as i dont see anything in this shot, though i want to know what the structure is, and what it was used for and what the other smaller structure is, is it a statue? im also wondering how you got the angle in the previous shot, as clearly its very high up and shot through trees, whilst this shot is very low and not shot through trees!
thats my thoughts, they are not technical or probably even helpful, thats why i dont normally say too much!
