Earth is round. Circles do not have straight lines on the perimeter.
Start worrying if women have no curves.
Are we done with astronomy and biology, now?
I think it's a 4:3 aspect ratio pic I see here, how nice to be able to shoot at different aspect ratios; I have the same camera with you.
But if I was to approach that scene... I'd go close to the blooming yellow plant on the foreground, place my lens from behind it and record it partially, keeping the orientation vertical and the aperture the same to get the sight of Exmoor and the sky filling the picture. The blend of colours, especially the foreground grass, as this specific season, doesn't seem to go well in the palette of your creation. Without realising it you have recorded contrast and colour interplay, blue and white on the sky, dark green and lighter green, green and violet, white and green, which are good; but the very foreground is a mishap. I have tried to crop it in my two mods, I hope the size of the pics will be allowed to be uploaded. If not, try cutting off 1/7th roughly of the total height of the picture from the bottom, leaving the yellow blooming plant in (some of it or all, the total area of grass then is not such a big problem in the chromatic symphony).
