@dyanisabelle, planning to book my first actual test before September ends. I heard also your recording and just to give my humble opinion, I agree with @Heprex mejo slow yung pacing, if you would hear some native speakers how they speak you can't easily understand because of the speed and some slangs and I think PTE computer designs to measure OF on the speed of speaking.
I tried to use Speak & Translate app in IPhone and I set the language to translate (tagalog to english) and noticed that some of my speech were transcribed wrongly in tagalog though I'm a native Filipino speaker so what I'd like to point in this is for sure sa mga native speakers meron din sa knila na may weakness sa pronunciation though native speakers sila of their own mother language. 🙂 Also OF must not suffer in expense of Pronunciation kasi usually pansin ko lng na mababa yung speaking kahit na mag excel tyo either OF or pronunciation pero mababa yung isa. Honestly isa sa weakness ko din pronunciation though mataas ako sa OF. Sa tingin ko speed or right pacing plus the right diction will cracked speaking, like sa singers blending with tune plus how you deliver your song prang ganon din sguro speaking sa PTE I dunno. 😃
