Remember, that in art like this, going for "realism" just doesn't worK (trust me i have tried to make it work)...
I strongly disagree. If you feel like going for realism then you should by all means add as much in as you can. Also, what do you mean by "art like this"? RPG Maker characters? Anime-styled characters? There is no such thing as two elements that "don't work" when you're drawing people for various reasons if you feel comfortable making it and you feel proud over what you've accomplished. That said I should probably contribute something meaningful to this topic as well...

The angles on the hands are a bit off. You have a very good perspective going on with the feet and they're angled nicely, but it doesn't show on the rest of her body. Don't be afraid to add shadows to her skin to make her look more "3D"! The secret to making anything look lifelike is to add shadows to it that emphasize what part of the body is closest to the person looking at your drawing. The proportions here are rather good. I would suggest focusing more on the hands for now, since they require quite a bit of work to get to look just right!
There's a rather subtle shading going on here which is a shame. You shouldn't be afraid to go all-out with things you are a bit unsecure with for the moment, it'll benefit you greatly if you go all out with shading and try to come up with as much contrast as you can. It won't look very good but you'll see how much more "alive" the character seems to be. I don't know much about chibi-stuff so I can't really comment on that, but it's a very nice detail you put on the hat there. Remember that details are important
Welp, you've gone with a pretty bold pose here. For starters, the shading on the cloak is pretty good. It would seem like your light source is above her because of the outer rim of her cloak and her hair, so it shouldn't be too bright on the inside of her cloak. Minor detail, but it's worth noting. The shading on the sleeves seems a bit random and like it folds a bit too much. Most common clothing doesn't fold quite that much, it might be worth putting a bit more observation into that. The hands here are pretty good actually, just remember that the middle finger is to be a bit longer than the rest in most cases. There's also an odd bend on the thumb, but it's rather minor.
What's most confusing here, really, are the legs. Her right one, to be precise. Because her knee doesn't really seem to be round it appears to me as if her right leg is twice shorter than her left one! You should, as was stated, place a larger emphasis on where the knee is to put to make the leg seem more natural. The boots are rather well made though. I would personally recommend you not to draw an outline at where the foot starts as it sort of messes up the dynamics you have going here, but it's still a valid option for adding a greater depth of perspective into the drawing. Your proportions are in order as well, however the left arm seems a bit too tiny in comparison to the rest of her. All in all it's a very successful attempt at a bold pose.

Now this is a nice improvment! The hair does come off as a bit "metal-y" because of how you shaded it but that's alright if that's what you're comfortable with it looking like that. Normally light forms a circle around your hair like a halo when it reflects off it, giving people a shiny circle around it (This is obviously for long, straight hair. It works differently on short hair which is irrelevant right now). As NAM said before your hands are bit too small in comparison to the rest of her body, but it's not that bad really and easily passable. Lots of people have tiny hands, after all. I love how you've added more shading to the skin, she looks more alive than the others so far! The ruffles on her clothing are very well-made, even if the shading is a bit lacking in contrast.
I'd say you're making obvious improvements here and hope I've shed some help into how you can push your limits a bit more. Good luck!
