As others have said, it is normal to get some water in your wing.
Personally, I find donut wings a LOT easier to "fully" evacuate than horseshoes and greatly prefer the donut since, as a videographer, I am constantly making changes in my depth and need a "fully" evacuated wing to stay stable while filming subjects on the bottom.
I also agree with IrishSquid about rotating from a vertical, feet-down position to a horizontal one as I start my descent. Personally I avoid a full inversion to head down/feet up position as a descent that way runs a small risk of introducing any grit in your tank into the valve's dip tube with the potential for clogging your valve and rendering it unable to deliver air. Not a high probability, but I've had it happen.
