The colours compliment each other and you have a cute little Iwaku sign in the corner.
From the little knowledge I have of it I believe the subject of the picture is the so called 'face' of the music creating/voice editing programme (whatever you desire to call it) 'Vocaloid' While the picture simplicity is nice it is clearly Photoshopped. The edges are rough around the animated character in some parts but they are not huge. All in all an okay avattar.
I do reckon though if you did the name Hatsune Candy in a Gradient, that could look really cool.
Well designed, matches your avatar, and it even fits within the signature space so I don't have to scroll. I can't think of any reason to dock points. Well done.
8/10 because it is a really great loop of a gif. I kept watching it to see if I could see a seam and couldn't. I don't know the character though but it was fun.
