After a while on the road Trixie had apparently run into some rumours of an unknown and great magical pony, so she puts her ego aside to train under the pony. Just so that she can try and best Twilight.
How will this end!? Can Trixy not only overcome Twilight and her magic, but also an Element of Harmony.
Actually self teaching when it comes to magic it can go one of two ways. One, either she becomes an extremely powerful magic user or she kills her self from not knowing too much about controlling the magic. It depends. If we put them both at their primes then it might be a fair fight.
Trixie feels to static in her pose. Her posture should more resemble a ")" so it would make it look like she is putting her weight down on Twilight. and adding to the energy of the collision. As it stands now it looks like Twilight is putting to much energy bracing / pushing back the force.
