Niholoid

While debating over what I'd like to cosplay next, i was torn between cosplaying Japan from Hetalia and various Vocaloids.

On Prussia's Blog, there was an advert for Niholoid, a parody of the Vocaloids, but with Japan.

Can't say I was terribly keen on the original Niholoid for cosplaying in the summer, therefore, I decided to design an outfit for Niholoid that looks more like the other Vocaloids. _{I based it off of Len Kagamine's outfit}

Any suggestions as to how I can make him look any more recognizable as both a Vocaloid and Japan the character would be much appreciated
