The deep footprint is because the moon is covered in very fine dust produced by countless strikes from rocks, which never blows away because there is no wind. The earth is protected from these rocks/meteors/asteroids by our atmosphere, which burns up most of them before they hit. The moon lacks an atmosphere, so everything impacts the surface.
The shadow in the first picture that is supposed to be from the flagpole, starts a few feet from the bottom of the flagpole. Why? Because it's not the flagpole's shadow. It's the shadow of something out of shot to the left.
The flag appears to be waving because it is crinkled from storage on the flight, and is only supported by the pole and the wire on top. The bottom corner of the flag away from the pole is just wrinkled and doesn't have a strong gravitational pull to straighten out the edge.
The fact that there is no crater is no surprise. The moon is not covered in damp topsoil like the earth. As the lander came down, the thick but very light dust layer was blown up by the retro-rockets, but later settled back to the surface.
No stars in the sky? Have you ever heard of light pollution? Trying to stargaze in a highly lit area does you no good at all. The stars are not bright enough to penetrate the glare from the ambient light. The moon's surface is lit by the sun and other stars are unable to penetrate the glare.
Come on, this isn't rocket science here people. Oh, wait...
