Yes. It became super obvious in the latest chapter (not official) where axel thinks back to her appearance at her coming of age ball, and her current looks. They used the old art in the flashback image. And yeah its not as good anymore, especially Aria. She went from looking cool, composed, and mature, to looking like a clueless child. I can somewhat forgive the other characters since their change wasn't as bad, but Aria and her female knight (can't remember how to spell her name) both got a HUGE downgrade. I'm also not all that happy that they made Axel look almost as childlike as Aria when he was also another character that has a very strong, confident look to him. I'm really really concerned that the art is gonna go the way of our little empress where the art started out really good, but after season 1 it quickly got worse and worse, until the very last chapter was simply HIDEOUS. I feel really bad saying something like that about someones art, but it ended up worse than even some of the more iffy manhua I've read. It looked like something I've seen middle schoolers with just okay art talent draw. Ugh idk I like the story so far, so I'll keep reading and hope that worst case scenario doesn't happen.
Did the art style change?? Its not pretty anymore
