Character Middle Aged Uniform Badge Distinctive Insignia

Create a character design featuring a middle-aged man in a dark uniform with a badge and a distinctive insignia on the shoulder. He has short, neatly styled hair and a serious expression, with his arms crossed confidently. The background should be a soft gradient of dark colors to enhance the subject's presence. Instead of a police badge, use a generic security emblem, and remove any brand names or logos. The uniform should have subtle decorations but remain professional and authoritative.
