The focus is mostly choosing the right colours for this particular character. While the pose is almost similar to the reference photo and this art has embarrassingly little of the details being captured, I think it would make sense to me to share this now as it is since it's a mere practise. Silly me.
Personally, in my experience with her, Bronya, in any battle suit is the most difficult character to maneuver. Either the timing is usually off, or I just couldn't figure it out. Nevertheless, it doesn't stop me to bring the best of her for you to see.
