About the size of Sejuani's model

I bought these days and used her to play a couple of games. After that I just found a problem. Well, not sure if anyone has got the same curious idea about it but the size of her model seems a little bit too small to me, comparing the other champions. Especially comparing because they are sisters right? The size of riding on her boar just looks quite smaller than the size of . I really hope Riot could pay attention to this question ASAP if anyone feels the same.
