Building a heat reflector or placing the fire in front of a natural wall-like (non-flammable) structure gives much more warmth, and allows you to keep the fire small. Even a pack will do, judiciously placed of course. I personally find eking the most out of a small fire is much more satisfying than building a larger one and constantly be watching the embers. Embers are the biggest danger. I remember as a kid burning tumbleweeds as they give off fierce heat for a minute or so, then going to the tent to find hundreds of tiny holes on the fly where embers had landed (this was near Mildura in the middle of more or less a plain of sand so no danger).
Also remember extinguishing the fire will take more water than you assume - take no chances and cover it completely with earth after you are satisfied you have poured on enough water, and then poured on a little bit more.
If you can, maintain a small pile of loose earth next to the fire, as well as water, to rapidly kick over any elements which seem to be getting away from you.
One tip I have read in a few places (but not tried) for lighting damp wood is to build an 'upside down' fire with large wood beneath and kindling/tinder on top. As said above, whittling back kindling (or creating a feather stick) will expose dry wood to get it started. The rationale is as the kindling burns, it dries the wood beneath, which catches from the coals falling down. It seems reasonable but I'm not sure how efficient it is in a real-life situation.
