Celestia vs. Grogar - Sketch

Ookay... I submit this, before I forgot. I want to see, what you think

Many FiM-fan imagine as Grogar fights with Celestia (mee too ). So I decided to draw their fight with fighting ponie-knights and troggs in the background. I added some accessories, because this is a serious battle ^^

I would like to color it, but I'm so afraid, that It would be not so good as I imagine this battle with fire and darkness...
Maybe later I will try, but my pc don't like drawing in these days -.- (the tablet is wrong and the mouse has some issues too )
