The first time I saw Brad Pitt was in 'Interview with the Vampire'. I love that book, and Brad was so stunning... really great looking guy...
This drawing was made with:
1. graphite pencils 3B to 8B
2. Kneadable / fine tip erasers
4. black marker (for background only)
5. Gelly roll pen (for fine hairlines)
Check how it was made here --> link
Thanks for looking!
