The face fluff style seems fine to me. The hands do look a little off at times,
mainly the fingers seem too long and the palm too small, though for the most
part, they look better than any of my hands. Lol. I'm terrible at them.

In these two:

the fingers look really, really long. Like E.T. long, or at least it seems like it. We
are so familiar with our hands and what they look like, but when drawing them,
it is so difficult, because the slightest thing off makes it obvious.

As for hairstyles, overall, they seem fine to me. Though in this one:

it does look a little odd to me, though I can't quite say why. I think
maybe that particular hairstyle clashes with the style of your faces. It
makes the top of her head look small compared to the big eyes and
puffy cheeks. At a quick glance, the rest of your hairstyles seems fine.

Hopefully, this feedback is useful. I wish I could offer more
advice about hands, but I have so much trouble with them,
I have the obvious habit of hiding them or making them
vague so I don't screw them up... =^__^;=

No it's useful, particularly with the hands. I never really noticed the fingers are too long until now! thanks for pointing that out :3

Other than those two, the rest of your hands are okay,
though a few might be a little awkwardly posed, but
beyond that I wouldn't call it "a major flaw". Just keep
drawing and they'll eventually start to feel more natural.

I've looked through your more recent posts and I see nothing wrong with any of the things people have pointed out. Why? Because this is your style and you are consistent with it. There are many artists out there who ignore conventional proportions just because they like the look. So what if the way you draw cheek puffs is similar to some Warner Bros. characters. And so what if you draw hands differently that the norm, and I don't see how they're horribly off. It's your style, and it's always evolving.

On the topic of hairstyles, if you seem to be drawing the same few styles all the time, then I suggest looking at photos and making note of new styles you might want to draw.

As for people telling you that these things are off, and I'm sure in their eyes they seem to be, so I'm not going to say they're wrong. They're just not seeing what they think should be there. So I suggest going back and seeing how many people are saying these things, and compare it to the number of watchers you have. You may find the number isn't as big as you think.

That said, if YOU feel these things need changing, then by all means go for it ^.^

Thank you for this very thoughtful reply. Indeed there are certain things I've done that have crafted my "style" and certain things I do want to keep. However, there are things I want to change. And I do like your suggestion of tallying how many people are making comments about specific aspects of my art, and make count of the people talking about each aspect. Good idea! :D

Happy to help :)

I agree with  wom-bat , man.

Nothing wrong with having a certain style, but there's nothing
wrong with wanting to improve or evolve that style if you want.

True indeed :3

Indeed :D
