It looks a little strange, but I haven't looked at the Moon from other perspectives to see if there's a bigger concentration of craters or not.

That's hard to say, Mars has ice covering both poles, and the other planet without an atmosphere hiding it from us is Mercury, but I don't remember if it has more or less craters on the poles.
Is that a normal occurrence on other planets too? Does Mars have a concentration of craters at it's North Pole too?
I think this may be a result of less geological activity on the poles, so while we see large areas (the maria or "seas") that are supposedly areas that were covered in lava and that have less craters, at the poles we don't see those areas, so we only see the craters.
Shouldn't it if asteroids & comets often come from that direction? The moon doesn't have a monopoly on being a target for these things I assume.

For some reason, this photo with all of those craters clustered there strikes me as being...I don't know....incongruous maybe?
If you think about it, you will see that having full coverage in high resolution is not something easy to do, but we have almost full coverage at 100 metres per pixel since the 1990s.

Wrong, we have colour photos of the Moon.
But the moon is just black white and grey, right?
That's because it's the north pole, and in the poles the sun is always low above the horizon, making longer shadows that appear as larger dark areas on the photos taken from above.

Such as why is it darker in at the center of the "spiral" of craters.

As you can see from the cut and splice, it appears to me they used linear strips focusing on the center and creating a pie in a sense.

That's because the satellite is on a polar orbit (otherwise it could not get photos of the poles), so it takes photos in strips from south to north, passes over the north pole, takes photos from north to south, passes over the south pole, etc.
