#1 Really love the clean shot of the Taj Mahal. Really clean crisp colors, nice reflections, just wish it was centered. I bet it's very hard to get a symmetrical shot (just a guess).
#2 The second shot I'm wishing that these objects continue indefinitely. I'd like a little cropped off the right side of the image to give the appearance of indefinite continuity.
#3 I like the space in the image, the simplicity, the lines, the spot on BW conversion, the framing, and the haze. Very good image.
#4 This is the weakest of the set, just feels like a touristy snapshot with too much going on. Doesn't belong in this set.
Also, please divide your images with spaces. You can edit your original post and do this in the editor.
