Gakkin, who works at Harizanmai tattoo studio in Kyoto, takes a new approach to traditional Japanese themes, strongly influenced by manga, graffiti and graphic design. But although his tattoos are definitely 21st-century, Gakkins still follows many of the traditional rules of Japanese tattoo art, such as: 'Never put momiji [message dolls] and sakura [cherry blossom] in the same drawing', and 'Tigers should always go with bamboo'.
While the background of this design is reminiscent of traditional Japanese prints, the colourful maple and the steaks of bright red on the koi makes it stand out as strikingly modern.

23. Jason Donahue
Artist Jason Donahue works at Liberty Tattoo in Seattle. His work often features Native American themes. His minimal use of colour is both subtle and striking, and his style looks great on both smaller hand pieces and larger coverings.
24. David Corden
When it comes to realistic portraits, there's no one better than UK artist David Corden. He's inked tattoo versions of everyone from Sean Connery and Harrison Ford to Eminem and er... Keith Lemon. Despite getting a 'U' in A-Level art (he was told that his work looked so much like a photo, he may as well have handed in a photo) and spending 15 years working as a ventilation engineer, he eventually followed his true calling in tattoo art.
Genko is known for putting modern spin on traditional Japanese tattoo art, although he insists that 'his style is having no style'. His portfolio of work takes in tribal, new school and greyscale tattoo designs. He's based in Japan and has won multiple awards for his work.
26. Adriaan Machete
Not only is this artist a sublime master of his craft, he also has a very cool name. Adriaan Machete is the kind of name you expect from a tattoo artist. Check out this awesome, if gruesome, leg design: vibrant turquoise against pink with clever line work make the characters pop.
27. Peter Aurisch
This design from Peter Aurisch is a great example of the artist's painterly, cubism-inspired style. His colourful, abstract works have put him in high demand as a tattoo artist. Aurisch is currently based in Berlin.
Shige is a self-taught tattooist based in Yokohama, Japan, and the founder of Yellow Blaze Tattoo. While the basis of his work is Japanese history and traditional culture, Shige has created his own original style, which he describes as a never-ending work in progress. His large-scale works are truly breathtaking.
29. Peter Lagergren

30. Ed Perdomo

He's currently looking to evolve his style: "I am interested in hearing ideas which may have me explore outside what you have seen from me," he says on his site. "I will be accepting all projects that catch my interest, and none that do not."
32. Anthony Romero
Also known as The Man With the Neck Tattoo, Anthony Romero is a dab hand at recreating haunting black and white portraits on his clients' skin – he's inked tattoo versions of everyone from John Lennon to Yoga. He also has a bit of a thing for horror – as you can see in the design shown above.
33. Ondřej Konupčík
Who says ink has to be well-defined and crisp? Well not Czech tattoo artist Ondřej Konupčík, that's for sure. He studied fashion before moving into tattoo art, and building up an international reputation as a master of the now super-popular watercolour tattoo style. As well as beautiful expressive tattoos, he also creates artwork.
34. Myke Chambers
If you'll excuse the pants, check out this intricate (and suitably large) traditional American piece of tattoo art by Myke Chambers. Coverage is very high but the colour work is stunning – as is the detail in the various animal and human portraits that run through the design. Chambers completed his first amateur tattoo aged 12 (shudder), and never looked back.
