this is bad
here is what you need to fix:
your proportions are off
you did not need the extra jump up in height after the calve it could have just went up
in addititon, the textures have no continuity
the hands have no collor change which is very jarring
the blanket looks like it is there for no reason
the chin is too pronounced
the arm is at an unrealistic angle
the tits a different angle than the shoulders
the eyes are too close to the top of the head
the hair goes at angles which hair never goes at
the hair forms a helmet around the eyes
the lips are too filled
the ears maker her look like a monkey
the face should have much more shade, and in general, in contrast to tthe background it is unclear where all the light is coming from, because that orm is definately not doing it
the cheekbone goes out too far
the witch does not fit the backgrounds texture and sticks out in a bad way
the eyes are just bad idk how to offer help on them just redesign how you do them entirely
you used enough blush to make it noticeable but not enough that it helps improve the drawin and instead the half haerted attempt at drawing it makes the artwork much worse
the hat is way too over the top cartoony which i could have overlooked if it was not for the fact that it does not fit the art style of all of her clothes
the nose is too shapy i guess (idk a good way to put it)
things that were good
the background is a good art style, keep it up
the pole she is holding has some very well done lighting
the glow is kinda good
i like the swirls in the background and its color pallete overall
if the girl didnt stick out like a sore thumb then the hat would be amazing
the hands having a white outline was a very clever solution to make them stand out and makes them pop out more in a good way
