I really like the photo of the statue, it has a very clear message of the great leader looking down on his people.
What kind of camera do you have, just your average point & shoot or a DSLR?
And I would try out some different points of view, for example shoot from much lower so you get the people standing in front of you in the photo too because from what I can see there's always people in front of you there.
Especially at the skyline photo it would've been cool to see all the people taking photos of the skyline on the photo as well. (kind of like what Martin Parr did at the
tower of Pisa)
In general try to get things either completely in or out of view or cut them a good way in, (not) showing just the edge of someone's head distracts from the rest of the image. Also try to get as close to what you're photographing as possible. Closer is almost always better for photography.
Sorry, I kind of went and commented on your photos instead of what's on them... >.>
