I finally took a decision, and it's that this FnL characters and big sprite characters, will get a new stylized models
Now they will look better as the Asgore above, tho, I'll limit the amount of effort on animations, there will be a limit of 6 sprites per animation
Walk, jump and basic moves will have simplier animations too, that to not put too much time on stuff that isn't that important
That'd also help to update incomplete characters, since it'd be easier and faster
In short, there will be better looking characters, and less worked animations
