GBPUSD reversal zone - shorting opportunity

Potential zone for shorting the GBPUSD with a harmonic, fib extension 1.618 and previous structure looking left. Also likely to be nicely overbought by the time this trade comes available to take. Great risk reward looking at coming back down to structure but would need a review as and when it comes into play. Other previous structure noted as potential to come back down to test those 1.51 lows. More of a heads up than anything.
