So here's the story:

'I foung this BEAUTIFUL scan of xxxHolic, but it was kinda 800x600 and blurred. I automatically thought I'll vector this. But when I changed the size, to my astonishement the work looked like a manga blob rather than a CLAMP masterpiece. So I started looking for something a bit bigger or less blurred. Well I found it, but it appeared to be cut (from half of yuuko's skirt, and just above her head, and some sofa on both sides) AND it had horrible colors (orange a yellow only). So I merged the two, and tried to do my best recreating the bits missing in the better scan (after all CLAMP is mostly about the lineart...) :)
After that came the coloring. Now, it's finished, hope you like it.
Oh the different colors of the smoke made me think of Mr Tulip from 'The Truth' by Terry Pratchett (confesion: am a big Pratchett fan). It look so chemical, it made me think of mothballs(don't worry if you don't understand... it's just my feeling towards the work)'
