>>65879563I do love the colors to this design, but I'll definitely agree with you by saying the outfit is extremely basic and non eye catching.
I'd experiment more with different hair styles. Locs or box braids don't flow like that. It would fit into the emo/grunge style if you included her roots showing.
I'd also look into fashion from that particular era, especially since digimon came out around that time.(?) I love the little robot face motif and I love how it's an accent in her hair. Try doing something related to robots for her outfit.
Here's my take.
