मिनिमलिस्ट ग्रेडिएंट फोन वॉलपेपर

A minimalist mobile wallpaper featuring [a solitary pine tree on a gentle hill]. Composition with generous natural negative space near the top and bottom, framed by a subtle vertical top-to-bottom gradient background. Clean, simple scene with crisp details throughout, no blur effects, no depth-of-field tilt-shift, and no cropping. Style: [minimalist vector illustration].
