Art Nouveau inspired illustration with psychedelic 1970s surf poster vibes, flowing organic lines, decorative floral patterns, stylized human figures and tropical motifs. Flat colors with bold outlines, limited shading, retro earthy yet vibrant palette (charcoal gray, burnt orange, mustard yellow, olive green, cream, maroon, coral pink). Composition should be decorative and harmonious, with movement and curves similar to Alphonse Mucha mixed with vintage surf art. I would like to add a rose (my moms name is rose) and also two game characters from garten of ban ban. The first character is named ''Tamataki & Chamataki'' and the other character is named ''banban'' (the characters from my son's favorite game).. The design must be a full slevee for a right arm. Use a retro earthy yet vibrant color scheme with charcoal gray #3B3736, burnt orange #D95B38, mustard yellow #E1A54C, olive green #6A6B4B, cream #F2E1C6, maroon #732F25, and soft coral pink #E37960 as the primary tones.
