To capture the iconic features of Alvin and the Chipmunks, begin by sketching their large eyes, small noses, and buck teeth. Use bold lines for their outlines, and accentuate their big ears and furry tails. Next, add their signature uniforms in red, blue, and green. Include microphones, headphones, and sunglasses as accessories. Remember their house and Dave’s house, and keep in mind their musical adventures, relationships, and cultural impact.
