Welp, it's quite a crude artstyle, but everything other is fine so whatever. Especialy if we consider the fact that every art by this artist is in the same artstyle and quality, and all were accepted.
Oh really? It's not really the pixelated thing (although it doesn't look good in my eyes). This is weird yes, but also the anatomy is not that great. The left arm's elbow looks way to far away from here body. Since the arm goes up in a 90 degree angle, her elbow must be located on the same line you draw, when you want to connect the left knee and the left hand...and that's not good.
That's why post #2435813 wasn't flagged. It doesn't show this flaw, although is more or less the exact same pose.
