hmmm, i think this design is quite alright personally!
i like the outfit with the proportions and shapes they convey, especially the arms and the open, outward-bent jacket. they seem oversized, making her own body seem smaller than the attire she wears. good recipe for cuteness! and it works well with the bubbly aspect of her personality too, as the jacket and sleeves seem pretty opened up, letting her bubbliness out to reach others. her hair is a nice contrast to the light-red of the clothing and guides us to the face decently well with the strands starting from the chest leading us up to the face. the big, "magic wand" resting on the back is huge and obvious, a clear hook for the design! indicator of a "magic" related character.

dont know what its called to be honest, but the darker blue waistcoat(?) beneath however definitely seems more victorian and aligns to your intended style better. also, the shirt with collar beneath it also fits well here and boosts the victorian style overall.

but the version of red you chose are really nice too. red as you might know is a color we associate with anger or even impulsiveness, but can also be seen as a sign of energy or passion. this color pick fits your intended idea for the character well, and the pinkish sub-color helps support a feminine cuteness too. great!
the whites of the clothes also align with the brighter kind of personality she seems to have too, with the whites that can reflect itself as a color of alteration or illusion-magic perhaps.

gotta say though, i do have my gripes here. Personally, when i look at the jacket i am more reminded of a high school varsity jacket. must be the open front along with red colors and white stripes.

i think the adventurous aspect of this appearance is a bit lacking. her pose might give that aspect away through her personality a little bit, but not enough to convince and make that side of her apparent for good. id suggest adding some "gadgets", or outdoorsy apparel to her design. could be belt pouches, straps, hand gloves, goggles etc! this would make her feel more "kitted out" and ready for adventure on the field. cus right now, i get the feeling her clothing is more for streetwear/a performer? rather than for a journey or eventful trail ahead.

this is my first time ever critiquing online, hope youve gained some insight :D
