GbpUsd Short Idea but be mindful

FX:GBPUSD   British Pound / U.S. Dollar
GbpUsd H4 Short idea with 2R risk. I've given the stop more breathing room due to higher TF, would usually consider above the engulfing formation.
Structure may be in fact be forming a bullish flag so be carefeul however direct technical analysis is telling me price should continue down without much of an upward push. Not great R/R however the plan would be to partially close profits at various levels and move Stop loss to BE after a certain amount of pips is achieved.
