GBPAUD Completing H&S pattern

Hello, this is my first published trade idea.

My thoughts on GBPAUD :

Price dropped massively after hitting a Monthly resistance (which confluent with Monthly Fibo 61.8), leaving a long shadow Pin Bar on the recent Monthly Candle.

I'm more on the sell side, but to verify that it needs to break the strong Weekly trendline as drawn above.

Yellow Line - Monthly S&R
Magenta Line - Daily S&R
