Shepherd Herding Sheep in a Mountain Valley

very realistic picture: have a sheppard wearing a straw hat herding his sheep and his back facing us up close with his sheep in the slight distance grazing on the field. he should have a frayed straw had, blue overalls, with rolled up flannel shirt sleeves. the background should be a vast and forresty mountain range with a field in its valley that has a lot of grass and flowers, there shoud be a shadow casted over the mountains and contrast should be high. make this a very realistic and cinematic picture with the mountains looking huge and mysterious. have the grass take up 1/4 or less of the composition
