Genkis
As for the "artistic license" discussion earlier in the comment section: ultimately what an artist working on a comission tries to do is find the "sweet spot" between the wishes of the customer, the color composition, and the general setup of the piece he or she is working on. For example the piece Genkkis worked on for me [link] the female character in the front actually has rather short hair (and I never mention whether she smokes or not; though she might actually start smoking after what she goes through
In the same vein, going with a gray treecat would've seriously gone against the wintery, crisp background color scheme (you wouldn't have seen the 'cat ^^ ) and taken away from the focus the "warmer" colors achieve through the contrast here. A black furred hexapuma in that composition also would have been, well, too distracting from the 'cat and the girl. Sometimes adherence to canon simply isn't the be-all and end-all of everything. Or do you think the placement of stars on this piece [link] really represents their actual, real-life location? *shrugs*
