To be honest, I didn't even notice that there was a change in art until I saw a discussion about it afterwards (though I was skimming, admittedly). Not like that sidestory they had with Gray; that style just bugged me.
Yeah. Sometimes when a new artist takes over it's jarring and hard to handle. Ueda seems to be doing a good job. There are differences but the characters still look like Fairy Tail characters and not sometimes own interpretation of them.
