Daggerfall enemies seem to simply move forward towards the player, no matter what it takes (notice how easily they get stuck in doorways if they aren't within a 22.5 degree margin of the opening). One thing I find interesting is how the enemies have sideways-facing, back-facing, and back diagonal-facing frames even though you rarely see them. They don't have to really turn. They just swivel around and maintain their front-facing frame.
Frankly when it comes down to movement, even DOOM's enemies were smarter. Well, or at least more fun to fight.

Regardless of the weird resolution of the blog images, something is a bit different with the HUD scaling for sure.
I remarked on that in an earlier post. The ones in the article are squished a bit to fit right with the blog's formatting. You're right though, even the "screenshots" page has them at a 4:3 aspect ratio which doesn't work right.
You ought to pursue some of the http://doom.wikia.com/wiki/Aspect_ratio that most DOOM source ports do in order to keep a proper aspect ratio, even when running at more modern resolutions.
