While the idea seems pretty cool, it was implemented in a mediocre way. The Gorillaz style does not mix when placed with the average anime style. They act like oil and water. Everything looks off in this picture with hardly any flow in the lines. What I recommend is too try to redesign Miku to sort of fit better in the world of Gorillaz. I know that seems almost blasphemes but it doesn't even have too be a big departure from the original design. Hell, it can even be the same costume but in different proportions. Overall; great idea, bad implementation.
