Very cute and it appears to be the only milk mustache entered. Probably should have used something a little thicker than milk though like whipped cream or even shaving cream to stand out though. Good job.
Cute, but an almost square crop on a portrait doesn't work well, compositionally. The background is also so close to the back of her head that the shadows of her hair interfere with the look of the photo by making it seem blurry around the edges.
Cute picture! But the photo seems a little blue-ish to me. Most likely from the camera flash. In my photo, I used whipping cream because it was thicker and whiter than regular milk. She's a cutie tho!
