A polished medieval knight helmet shown from the front, with a clean, smooth metal design. One eye shines through the visor slit, glowing softly with a red fiery light — bright, powerful, but NOT creepy or realistic. Behind the knight, an old WW2-style cannon sits horizontally, and a large medieval blade is crossed behind it like an emblem. The background features a dramatic explosion of glowing energy in blue, red, and touches of green, creating a bright shockwave effect. The overall look is heroic, bold, and semi-realistic, designed to stand out clearly as a YouTube profile logo. No text, make the knight realistic but the eye cartoonish.” See more
