This is a very gorgeous portrait art of our favourite Vocaloid, albeit radically re-invisioned (She's very austere & has a sophisticated air, whereas the original focuses on dynamic energy with bit of dorky charm). But this works wholly in favour of her, and delicate linework fused with vibrant colour layers & gradations make for a very wholesome and richly warm characterization. Also the choice of styling, a more dressified variant of the Append style with its fleshy ribbed design is perfect in adding more depth & organic flavour to the lush excess.
One small gripe is that her arms & hands are too skinny and tiny in proportion with the wholesome torso and head. Still it's just a tiny aversion and compensated by the aforementioned lushness. Great job on this, a characterization both memorable & soulful!
