There are some designs that I like quite a lot in these portraits. There are some that I just like. Some that I find a bit "meh". And there is this design of Suwako that I just cannot get used to, because I think it really doesn't fit her at all.
I know that there is some sort of delirium of her being a "loli", here and there. This portrait (as well as her battle sprite) just emphasizes this too much and removes any credibility out of her, especially when you start reading dialogs.
