I see a lot of pilots flare early (50'), that almost always leads to an increase in thrust (AT is in Speed mode). Eats up runway fast. If the AT is on, reduce TLA to stop/limit power increase around 40', start to flare around 30', and don't prolong the flare, but work it into a touchdown as soon as you can. I sometimes get a great landing, but (almost) never land long.
Also (company procedure permitting), if you use full reverse, don't go from full reverse to forward idle as the engines will still be spooled up, wait at idle reverse until spooled down before closing the buckets (or sleeve...).
Good luck!
