Recolourisation of Kristina portrait

Back to my old specialty for the first time in two years with a recoloured version of a portrait by David Beck of Queen/King Kristina of Sweden. She is the reason I've been less active on DeviantArt (mlpfan1982 and TheEclecticOne) and Tumblr (malenkaya-glosoli) in recent years. The original is available in colour but the only digitised image I can find (at the Danish State Art Museum) has a sickly green tone that doesn't give good colour adjustment results. Recolourising done by me in ibisPaint X on my iPad (I don't currently have access to Photoshop or a good PC).
