I like the old protagonist AoA picture more, but I think the rest work great. I enjoy it when Soejima gets a little more cartoony and stylized.Looking at the new AoA shots, there was definitely a change in vision there at some point. It's easy to tell when you compare the two:
They changed from being over-the-top/cartoonish to being less exaggerated and more grounded. I personally had no issue with the energy of the former, but I guess this is what they thought would be best. It kind of makes Ryuji's and Morgana's look out of place now, though.
