In these situations I often shoot manual exposure (and flash) for total control - in the first example you posted although you may have the camera set for -3 EV, but there's no way that that background is exposed at -3 EV - ... in fact if anything the highlights are close to blowing - to me it it looks like it was set for normal metering - so perhaps you didn't set the compensation as you thought, or the camera metering got it completely wrong? At -3 EV it should be looking like a dusk shot. Equally, if the subject was flashed at +3 EV I'd expect him to look more washed out in this circumstance. Getting the balance between foreground and background is critical to avoid over exposing the foreground or isolating them too much from the background (unless that's the effect you're after). Often the easiest technique is to put the camera in manual mode - get the background where you want it (without the foreground subject / model there) (drop it down 1 to 1.5EV from normal) then introduce your foreground model and just tweak your flash exposure compensation (or use the flash on manual power) until you get it right (this is where light meters win every time).
The second shot is a great effort because the background by itself will probably push the sensor past it's usable dynamic range (so you're gunna have to choose whether you lose the hightlights or the shadows) (highlights are close to going) - but you've also got a high contrast foreground with the lady's black coat through to much brighter elements - so deceptively tricky conditions that worked out pretty well all things considered. Again, if you've got the time, shoot manual - get the background right first - and then work on the subject & flash.
Hope this helps,
