I think this is one of my best pictures. It was quite difficult, but worth it.
I think I could have made the background much better, but the file was getting too big, and my ancient computer could not handle more than a few layers at this size.
I made her lightsaber blue because yellow highlights would not show up well on her suit. Also, fun fact: blue lightsabers are the best.
Since I tried really hard on this, please leave a comment, and please don't steal this picture.
