The second coloured version I did of this pic that Jace drew of Sedary having some fun with a pair of uni twins :)  I liked the first version with the black ones, but it was kinda hard to 'read' their forms as well.  I also like ivory white unis as well, and wanted to do a version of them to satisfy myself, and to make it easier to see.  The background was inspired by the style of some of Jace's as well, with colour pencil over coloured paper.
