First I traced it through and added a bit of shading.
Wetted it and 'smudged' the colour up a little (still not happy with the bleeding but I might have to live with it)
Then it's a matter of choosing the right colour. (or colours)
I did another one but with Textile Medium. I have to wait 24 hours before I heat set it to see how it comes out but it doesn't look very wonderful so far.
