You gain my respect for two reasons: 1) Its Jade performing a cool kicking pose in a nice angle. 2) The use of MS Paint or something of its like and make it look decent.
After having said that I still have a few comments. The lack of shading has been mentioned, but I can't help but noticing you've made her caucasion as she was in the old Malibu comics (I believe it was the Malibu comics she appeared as white skinned, please correct me if I'm wrong), and not making her appear as the dark skinned beauty she is... How come?
