In particular, this is one of your photos I most liked from your portfolio, maybe because of the colors, or maybe because even being so "empty" it says a lot. But I also liked many others of them, like "bottle", I love its color contrast, or the "toilet paper", it's great!
I also like take photos like "camel", using wide-angle lens very close of any point of the scene, or also like "streetcar", also the colors of "urban" (it gives an awesome unreal atmosphere) or "M and Ms" (I have also been in New York ;-) ), or the filling that "Rotevatnet" transmits.
I cannot give you a very professional point of view of your photos, because I have still to learn a lot about this, but I can assure you that I have enjoyed a lot watching your portfolio!! Good work!!
