In reply to Adam Long:

That Twitter photo looks completely wrong to me, especially compared to your photo. Yours is a half-moon whereas his is waxing gibbous, a few days closer to full than yours.
Over flat land, you'd expect a half-moon to be rising at noon and a full moon to rise at sunset. So a half-moon would be at its highest at sunset, and a gibbous moon closer to the Eastern horizon. A full moon rises as the sun sets.
The shadows suggest the sun is in roughly the same position relative to the camera, close to the horizon out of shot on the right, in both photos. So a fuller moon should have risen more recently and be closer to the horizon towards the left of the picture shouldn't it?
The Twitter photo shows a gibbous moon much further along than your Froggatt half moon (which is a lovely picture btw); in that position relative to the Sun it should be waxing crescent.
