Minimalist tattoo sketch for the ribcage side: a stylized skull wearing the beret of the Russian Marine Corps; the beret features a small official-style emblem (subtle, not overloaded with detail). The composition is vertically elongated (10–12 cm height) to follow the rib curve. Clean black outlines only, no shading, no gradients, high contrast. Style: clean line art, vector-like quality, maximum readability from 2 meters. White background, no texture.
