Sorry that I didn't share this early, I have to make this secret to surprise everyone.
Personally, I hate to make a traditional magical girl since they are too... sweet. With all puffy clothes and bows, I hate to make it since they are so overused. So came up with my own idea on making it simple while keep the element of magical girl - cloak, pose, ward, magical stone (Uranium), expression.
It went better than I expected and everyone seem love it. :)
