I pretty much always write in present tense.  I don't know if I do it well, I prefer to let others judge for themselves.  I also think it adds an extra sense of immersion and immediacy, and enjoying reading present tense as a result but I've also always been a super-odd person.  To be perfectly honest though, I don't write in present tense to create that extra sense or for any other artistic reason.  When I'm really writing at a pace where anything gets accomplished it tends to feel like the most pagan thing possible.  Like I'm the center of my own little magic ritual that's causing scenes to flood into my head of me to the extent where I don't have time to think about stylistic concerns, I have to keep my pencil moving against that paper faster than I thought my hand could move just to make the words keep up with the reality unfolding before my mind's eye.
