Man, I am SO glad I put you on my watch list! This is gorgeous! Everything in this piece is just beautiful. The shading and colors really give off that warm feeling, and the expressions are perfect. The variety of colors that you used to help you in the shading really enhance the lighting of the piece. (The color palette could have a bit of a larger span, but I think you managed to capture your desired mood just fine here.) I have to say, you did a very good job on Angel; I think this is one of the few times I've seen him shaded so that he actually looks like a real bunny rabbit and not a flat off-white blob--nice job on that one.
But I think the selling point on this piece would have to be the sparkling, "halo" effect on all the lights--they really seem to frame Fluttershy's face and bring out that tender, heartfelt feeling. Might I ask, are those supposed to be fireflies? or something else? Either way, congratulations on another successful piece! (instant-fave!) Glad I got a chance to enjoy it before the EQD crowd inevitably caught a glimpse.
