I'm not an airbus driver so I cannot comment on the specifics of landing an airbus, for that you need to have a thorough read of your flight crew training manual.
A couple of thoughts though.
Remember what you are aiming for, a positive contact in the right place at the right speed. You want to be able to achieve this every time. Trying to grease it on is a mistake and will lead to trouble in poor weather conditions as you will then struggle to land correctly as you have not been practising it. The passengers and cabin crew are not good arbiters of a landings quality.
Pick your aimpoint and drive the aircraft towards it maintaining the descent path all the way to flare (use Papi, glidesope indications to help) and try to avoid overcorrecting close in. A-lot of people are ground shy and shallow off their approach in the last 50-100' pre flare but then flare the standard amout, result long landing. Scan aimpoint, speed, aimpoint, speed repetitively occasionaly taking in glideslope & power setting as required, you can largely do the later by feel.
Next look to achieve a consistant flare technique. Airbus will detail this. The cadence of your rad alt countdown may well help achieve the correct flare point as will looking ahead. On most types you will want to start reducing power to idle as you flare with the aim being idle as the wheels touch.
Keep flying the aircraft on, don't just flare and wait in hope, if you don't achieve touchdown adjust things.
If you detect a large sink rate developing late on use power to cushion it, just as the power bites take it off again to avoid floating. Avoid overflaring to cushion as this may lead to a tailstrike.
Good luck
