Half Fast Drivr

This is a two-parter.
First, my drivers side headlamp seems to always be lower than the passenger side. Even after using the adjustment screw on top, the light works its way back to slightly lower than the other side. Any idea what would cause this, and what the fix is?

Second question. The shape of the main focal point of my headlights is a slanted line. However, it is slanted the same on both side. So, the image appears on a wall like this... / /
Shouldn't the two shapes either be flat like this - -, or at least opposites like this \ / ?
It makes me think a bulb is installed incorrectly or something. Any ideas??

Here's a pic (hopefully) of what I'm referring to:

Looks correct to me. The angle is caused that way to prevent blinding oncoming traffic on the left. Usually in European and UK vehicles that may go to other sides of the road (think French car driving in UK) the angle is adjustable - electrically or otherwise. Or place stickers on the front when you travel.

By default though for a North American car I think your angles seem correct
