Tactical character in lime green jacket

This image features a sequence of four character poses for a tactical, sci-fi action character. The art style is high-contrast digital illustration with clean, sharp lines and a saturated, vibrant color palette centered on neon lime green against a solid flat blue backdrop. Each instance shows a male operator wearing a skull-patterned tactical half-mask, high-tech infrared night vision goggles, and a NASA-branded lightweight jacket. The character's gear is detailed with realistic tactical touches, including plate carriers, pouches, and complex footwear with glowing light accents. The progression of the poses suggests a movement sequence, moving from a standard patrol hold to a high-ready stance and finally aiming down the sight of an assault rifle. The lighting is uniform, resembling a professional character design sheet or concept art for a video game. The overall mood is cool, aggressive, and highly stylized, emphasizing the character's functional, high-tech weaponry and urban, futuristic aesthetic.
