Love gift for your fiend there MikadoSaya and not too shabby either on your take of Fluttershy from MLP, always a busty one she is. ^o^
Well one thing is for sure you really nailed the cuteness of this character and just as well a whole new look of her with a bit more human then pony this time around! Makes for a nice blend of both worlds where you still keep some of her elements like the pink hair, the yellow wings, but even nicer on the addition of her more curvier lady parts as compared to her tinier self on the show, wow!
Do like that nice close-up shot you went for here with Fluttershy really focusing in on the viewer and damn those are just damn near impossible to be drawn away from. That anime touch to her especially with the face, eyes and the rest of the anatomy on her makes for some good ways to expand upon her so you can further her cute factor even more then before, very clever.
Nice show as well with your coloring for alot of the fact you utilize some light shading techniques and some additional lighting to draw in even more appeal to both her and her body. By that I mean like on the wings where you make it seem more fluffy with the shading done there or even around the top of the forehead to show that way she always is trying to hide. If anything it indicates good direction of light and other areas like the chest, those little shine makes definitely make those rounded areas alot more voluptuous to look at! o0o
Already did mention this before but hats off again to your work on the eyes. The deep blue tones your used are very satisfying and definitely make for a beautiful effect with the way you make them shine, bravo MikadoSaya.
Last but not least a nice job on the hair itself. Giving it that full and thick look with the many threads all over the place and other areas where you add in a slim shine of light like most animes would do make the hair seem more detailed. Plus some bonus points towards that adorable and also rather sexy idea for her top with the little butterfly for the pendant.
Really wonderful work done here MikadoSaya, you are quite the gifted artist. *nods*
