Ideally, they wouldn't be static either, but I prefer the static look to the way Chuckles does it, because the moving quills draws attention to the flaws much more than the static quills do. 742mph explained it well.
That's the worst way to possibly get something to look
good. Just because it might look pleasant to the eye, doesn't means it's appropriate or even logical. It's just like saying that Tails' tails should stay static because it shows flaws when moving, instead of wanting to go for something more dynamic and logical for the character, not to mention it's lazy and dull. By the way, you never pointed out what the flaws were, you have just been talking through the topic that you didn't like seeing the back of his head. I'm not surprised that this turned out to be the case, because you could never see the back of Knuckles' head that much in classic games, so of course this would be a first, and it's something you would need to get used to. But making his dreads static is the worst option possible, and I don't intend to change it just because you
think it's better.
Why is it worth complaining over an echidna's sprite? Chuckles is the perfect version of Knuckles for 2.1. Also, why are we complaining about a Gliding echidna's sprites? He's fictional, it doesn't matter if his animations are weird. He anthropomorphic, he sides with a blue hedgehog that can run really really fast, and a fox that has 2 tails and can fly. I want this reply to end this argument over Chuckles' and Knuckles' sprite animations. It's no reason to change or argue about, he WILL be in 2.1, and you're just criticizing the artist that made him. Also, if you don't like the sprites, Make them yourself!
Summing up your post, you are just saying "IT DOESN'T HAVE TO MAKE SENSE BECAUSE IT'S FICTIONAL", and kinda being rude in general. If you wanted to end an argument, that's the worst way to do it, and it wouldn't work either.
On the other hand, what has been said in here about Chuckles was barely criticism. All that I have read in here was mostly related to "I don't like seeing the back of Knuckles' head" or "Chuckles is bad because SRB2 Riders Knuckles did it right". Whoever said things like this is basically just giving out opinions, and is not constructive at all. There wasn't any explaining on why it's exactly bad to see the back of Knuckles' head, there wasn't any explaining why the dreads should be changed, everyone with that in mind just said it
should be changed. The final version of the back of his head are honestly the finest I could get, and I'm happy with it, the back of the head while running being based on Knuckles Chaotix reference, and the back gliding being made to replicate what his side sprite on Sonic & Knuckles is (with a big help from Jeck_Jims). It looks good and it looks accurate to how it should be, that's enough for me. If anybody has any decent criticism on how it can be improved and made better, I'm all ears and willing to change it if your criticism is decent. If not, do us all a favor, stop being persistent about it, and please, get back on discussing about the upcoming 2.1 release.
