Oasis Spring desert, rocks and background realistic override

as the title says i'm looking for a texture override that can make oasis spring more realistic, i really hate how the rocks look "fake" and the mountains in the background are too cartoon style, i have all the realistic mods for grass and sky in willowcreek, newcrest and granite falls so i want a realistic thing for oasis spring too XD (if there's nothing someone can tell to me where to look in sims4studio to do it my self??)
