personally, i'm going to say that the hdrs here are overdone, esp the later ones in the first page (namely, sapporo continued), there is so much haloing/uneven lighting which is impossible!
the color saturation is also a tad haphazard. note that this is if you are going for a realistic look, i.e. increased dynamic range but still natural lighting. the attempt here, frankly, looks to me like an attempt to simply "make bright points dark and dark points bright".. not all the composition is weak but i think compositional strength is a tad erratic here.
and i hope i don't sound anal about tilts and all that, but they are easily corrected..
surrealistic hdr can work, i have seen some good examples in
angelreich's portfolio, but these here, they do not work for me - there seems to be a lack of direction as to what is sought to be achieved from using the hdr technique other than a scrounging of massive detail from the scene.
