4. Bob Tyrell- black an gray artist he is an inspiration to me cause I love to do black an gray tattoos .. Bob Tyrrell is an incredibly talented artist specializing in horror imagery, portraiture, and realism . Having entered the industry at a relatively late stage he has quickly shot to fame under the tutelage of renowned artist Tom Renshaw . His work is heavily influenced by American sci-fi and fantasy artist Frank Franzetta , and his pieces are proudly worn by many well-known musicians including singer Kid Rock. Known for his horror themed black and grey images, Tyrrell has the enviable talent of creating work that appears to leap off the client’s skin. His portraits are characterized by eyes that can follow a person round the room, an effect which many artists struggle to create. Based in Warren, Michigan, he spends much of his time on the road at various tattoo conventions and has appeared in both LA Ink and London Ink documentaries.
