A wild, untamed desert with massive sand dunes and a violent sandstorm raging in the distance. The sky is dark and ominous, filled with swirling sand and debris. A lone nomad struggles against the wind, their cloak whipping around them as they push forward. (The oil painting:1.7) uses harsh, gritty textures to convey the raw, unforgiving nature of the desert, with a stark contrast between the desolate landscape and the nomad's determined figure. 4K, masterpiece, ultra detailed.
