I'm no photography buff. But I've learned one thing about shooting DH. Pictures will never show how steep, difficult, or big a spot is. Light is a bigger issue if you don't have remote flashes. Then, you want it to be somewhere that riders find difficult. Since that's where they will be the most animated. Of course there are a couple jumps too. Everyone loves a jump. Personally, I like shots that show a cheering crowd around the rider.
