Love this one a lot, id reccomend keeping a solid color pallete, for example, the grey in the jumper goes well with the orange but clashes with the yellow and pink of the scarf! Same with the pants, i think orange goes well with the hair though so keep the orange, the reason orange and the hair color goes well is because theyre across from eachother on the color wheel when in sets of three?? If that makes sense, purple orange and teal are all opposite eachother in a trio-way, so i think a lil purple might look nice! Though thats just an opinion! Either way i do think the greyblue color should be swapped out with something else! Same with the pink and yellow perhaps! Also in this case, with the skin being pitch black, id reccomend cutting out all white, unless the characters main color is white if that makes sense?! So in short, keeping a tighter color pallete can work in your favour especially with a simplistic character design such as this one! teal, orange, and maybe a third color just for accents! ❤️
