Twilight Sparkle- Losing Control

Sorry for inactivity! My photoshop has brush lag almost every time I go on, so it's really difficult/frustrating trying to sketch a drawing with broken strokes. However, a few days ago there wasn't any brush lag so I was able to begin drawing something c: I thought the idea of Twilight experimenting with darker magic would make for an interesting drawing, so here it is. Hope you all enjoy!
