iPhone 6s EPIC REPAIR FAIL!

I tried to open up my old iPhone 6s to perform a dock connector replacement, but when I was pulling off the screen, my plastic pick to separate the display somehow got in between the digitiser and LCD, and caused damage to the LCD and the LCD also got ripped off the shield and ripped the home button cable! What went wrong do you think? I don't really care it's broken since I had it for years before I upgraded.
