#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.
Good variety of shots. Keep shooting.
