No, but Ricken and Inu are the same person, as seen here. Quere and Ricken/Inu are easily confused since they both have very anime artstyles and they both used that anti-alias oeaki look at lot, but I would say Quere's style was a bit more shoujo-ish. Quere would always emphasize very sharp line and chins with long, lanky, angular bodies. The image you posted is one of Quere's, I believe. Ricken's Gorillaz tend to be more boyish and less overtly feminine, and she'll often draw them in more dynamic poses and settings than Quere usually does. They both shipped 2doc, but Quere was a lot more lewd about it, and I'm not sure that Ricken ever posted outright porn of the two while, Quere drew loads. Ricken has gone on to professionally draw ottermode shota cape comics, and while her preference has definitely shifted more in that direction since her Gorillaz phase, you can tell even then that her art erred more on the side of boyishness than prettiness. Ricken/Inu was also more consistent in signing her art, so you'll usually know if you're looking at one of hers, although I have see a rare few unsigned doodles.
