For me it would be Venus/Moon as dominant planets, followed closely by Mercury (Moon and Mercury are in mutual reception), as dispositors of the chart elements.
Moon might be more dominant because of being elevated above Venus (and Mercury), also being master of the night (this being a night chart); however, Moon is posited in its house of sorrow (whole sign 9th house), and cadent (9th house); Mercury too is in its house of sorrow (7th whole sign house), although strengthened by being angular. Venus is in a succendent house and, unlike either Moon or Mercury, is in its domicile ("rulership") of Taurus; Venus also posits a Bright Degree of Taurus.
So, if pressed, I'd have to say I consider Venus the likely lord of the nativity, but I think for practical delineative and/or predictive purposes I would consider Venus/Moon as co-dominants, with Mercury as completing the "trio".
