Create a grid of nine hand illustrations, each showcasing different hand gestures. Alter the hand positions for uniqueness: 1. A hand open wide, palm facing forward. 2. A relaxed hand with fingers slightly curled. 3. A pointing gesture with the index finger extended. 4. A fist with the thumb wrapped around the fingers. 5. A hand with fingers splayed, palm facing up. 6. A gesture mimicking holding a small object. 7. A wave motion with fingers raised. 8. A hand making a 'peace' sign. 9. A symmetrical hand gesture, such as 'OK'. Use soft colors like pastel shades and remove any brand references or logos, while maintaining a clean, sketch-like quality. The background should be plain to emphasize the hands.
