The real question is Mila's blue-hair (that consequently bring you to use the white in the jacket for "balancing" the colors matters): even if you like this color, many people naturally will be recluctant to it, used to her ordinary red's hairs of Mila (by the way a distinctive trait in the roster of DoA).
If you want keep the blue hair my suggestion is to color a main big drawing of Mila with the black and red colors (so to give the main focus to the standard image of Mila, the first thing that will meet the eyes of the fans when will atted to your drawing), then to draw on the side a Mila's version with blue hair and the white jacket (not necessarily a full and big entire body, even just a smaller one only from the head to the waist), proposing it like an
alternative to the main version (through the press of the imputs on the controllers, other people have already submitted fan arts with "instructions for the use" inside XD).
I know that this is a "come to terms", but for me this is the best solution if you want keep the blue hairs and to hope for the like of the majority of Mila's fans (according to my thoughts, of course).
