Uhh...hmmm...
I would give you some advice but without a HUD I'm pretty much useless...
j/k -
I guess you should ensure you are looking down the runway at the horizon and use your peripheral view to judge your touchdown...possibly try to perfect your power on landings first and slowly move to the more difficult power off landings...buy a book by Rod Machado?

At UPT the IP would reach over and yank your O2 hose on your mask when you were doing things wrong...that seemed to make things stick in my head.

Good luck!
