#1 - Too noisy for my tastes. I don't really care for HDR shots too...the haloing around the buildings looks weird. I don't mind HDR shots when you can't tell they're HDR.
#2 - I like the colors but the horizon is almost right in the middle of the shot. Nice that you put the sun to the left and not in the middle.
#3 - Doesn't do anything for me...too much dead space above, cut off feet, no face, bright spot drawing the eyes away from the subject, the degenerate reaching for his crouch...least favorite shot.
#4 - Interesting shot...lots of colors, good capture of movement...just too much noise.
#5 - Looks like a nice shot but too small to tell.
#6 - Decent fireworks shot. Looks like there is some camera shake going on though...handheld?
#7 - I like the B&W conversion but don't care for the subject matter...the two people look more like one big black blob than two separate individuals. Picture would look great without them.
