I'm always in awe at your attention to details. That dragon tattoo is amazing! All the individual scales seem to stand out. I also really like that circle design in the background with the beautiful flowers, though it's a pity that we can't see it very clearly.
This is a beautiful piece of art, the shading is beautiful and the colours go well together. The image itself ("lineart" for lack of better word) is also outstanding, it makes me think of "Gakupo" (the Vocaloid) but has a different aura altogether. Beautiful.
