I drew this based on the real photograph of SNSD, hehe. However, I couldn't draw the details, it will be too ugly. This picture is my favourite because they look so charming! I like Tiffany's and Sooyoung's hair. But I failed to draw Yoona's hair correctly ^_^'
The picture is a bit blur, haha. In case you don't know the real picture, here it is.
