They pretty much improved the animation aspect of flipnote studio by giving a bigger canvas, more colors, and 3D depth support, but what's even the point when the whole online community aspect got cancelled internationally and the game was exclusive to club nintendo members for a sizeable portion of its life. I think Nintendo got scared from the great swapnote spotpass scandals and just decided miiverse was enough to moderate as is. You might be able to share flipnotes through streetpass but that had never happened to me in my entire time of bringing my 3DS to high school so that sure goes to show how effective that was. It's a good animation tool for sure, but I just can't think of it as anything other than a complete disappointment with immeasurable amounts of wasted potential.
