I like the designs on the border and the color contrast. However
her proportions are a bit weird. Like how her neck is longer than her head, but that could just be the style. The water mark and
and Mami's name, while certainly not the worst, are really unneeded and distracting. Back to the compliments (because
I don't want you to hate me) you really captured her costume
with the attention to detail and the coloring only being slightly
diifferent from the original palette, which I'm pretty sure you
did on purpose to make the yellow and purple go together. So
in conclusion mostly solid work and thank you for request.
