Long Hull, Tall Periscope
A slender teal submarine floats beneath dark rain clouds, with a towering bent periscope and loosely painted sea.
Small 640×640, Medium 1200×1200
Square editorial illustration of one surfaced submarine seen in strict side profile, spanning the lower third. Exaggerate its hull into a very long, narrow teal capsule with small rounded ends; a tiny offset conning tower supports an absurdly tall periscope with a short bent tip. Keep the silhouette unmistakable and readable at thumbnail size. Expressive hand-drawn dark marker contours surround broad impasto-inspired painted fills, with just a few chunky paint ridges, no intricate texture. Two sweeping slate-blue strokes establish the sea and partly conceal the hull's underside. A charcoal storm bank hangs in the upper left, contrasting with pale warm-grey open sky around the periscope. A few widely spaced rain strokes suggest wet weather. Restrained teal, charcoal and ivory palette; playful proportions, quiet composition, ample empty space at upper right. Finished artwork, not a diagram or icon sheet. No people, text, logos or watermarks.
