One of the best 'sleeves' I've ever seen was a full arm piece, all brightly colored, fresh fruits and veggies (all very realistic looking) very clean lines, with like a Japanese greywash throughout. I will post a photo if I can find one of this tattoo. I loved it, and would like to create a similar tat, but with the veggies actually spelling out 'Vegan' or have some type of Animal Liberation message as the negative space area of the tattoo.
