Actually your time of birth was incorrect it is actually 10.45PM place of Birth Lewisham London UK, his ascendent is actually Scorpio with Neptune in the first house, which I would guess is why the media and others may not really have seen the true core personality. Those with Neptune in the 1st house often seem to have a transformative element to them, and with also been in a water sign a certain fluidity of personality is probably what help make him able to adapt and be a darling of the fashion world and celebrities, however it is also probably what hid how distressed he was about his mothers death, so family and friends didn't see the suicide coming.
Also Neptune on the 1st obviously made him a person who was very deeply affected by his emotions, he also had his Moon and Sun in Pisces.
The Transit occuring during his death, show no activity directly in the 8th house there is just a Saturn Sq to his Natal lilith in the 8th House, and transiting Pluto in opposition Natal Lilith in the 8th. Transiting Saturn is conjunct Natal Uranus as well at the time of his death, which I guess is unexpected death, or a block to his normal eccentric lively personality which was obviously causing him frustration.
I found source for his Birth data from Astrotheme, and ran my own chart with transit at time of death, see attached, I used placidus system, but would be intrested to see others take on his chart using other house sytems.
