Honestly I'm on the fence about whether or not I should stay with old art style for my manga or new one. I've been told quite a few times that the old one wasn't good, but honestly it looks fine to me.
I'm no art expert, nor am I trying to argue against the claims. There are most likely flaws that don't really bother me.
I was considering going with a new artist (also for cost reasons) and right now I only have a few rough sketches from them, but I'm not sure what to make of it.
Below is an example of the 2 styles of the same character who is 7 years old in both images. It is supposed to be an action shonen manga.
