Realistic Live Wedding Sketch Artist

I'm in need of a skilled, realistic-style live sketch artist for my wedding reception. The artist will focus on sketching candid guest interactions.

Ideal Skills:
- Proficiency in creating realistic sketches
- Experience in live event sketching
- Ability to capture candid moments

I am looking for someone who can not only draw well, but also interact politely with guests and remain unobtrusive during the event.
