Something just jumped out at me... So I shall poke it *pokes*... and not I'll tell you what it is ^.^;

On the right side (of the image) her shirt is pulled back a bit... makes sense because of the pose and hand... but the shirt side on the left is twisted way behind her back... what's keeping it there? It doesn't seem like the shirt flap would naturally lay that way, to me.

By the way, I love how your art style reminds me of Korean art. Especially the face. Like the dolls on ROIworld and such. ^.^
