Not sure which point you're trying to prove but here's some advice from what I saw:

Map awareness - While you were farming in the jungle, one of your teammates was trying to defend a goal against that Charizard. As soon as you saw that pop up on your mini map you should have went over to help. Because you stayed in the jungle and farmed, the Charizard was able to score, likely allowing him to get enough points to get his Ult up (which is what killed you). If you had went and helped immediately, he might not of had his Ult up and it would have been a 2v1 rather than 1v1. Sometimes you just have to give up farming, even if you're halfway through killing a jungle creep, to help your team out. It's worth it in the end.
