Time for more head canon! :D
 
I imagine Twilight would be only slightly larger than the average mare, but still barely smaller than Applejack. Soon enough she will be about Cadence’s height. :3 I also love her rainbow power colors, and I think that as she matures into her alicornhood these colors would start to show themselves in her mane and tail, fetlocks and her wings. Her horn would also start to grow. I like the more traditional interpretation of unicorns – cloven hooves and having a long tail, specifically – so Twilight definitely has those, as well.
 
That’s all I’ve got for now. I’m not getting deep into personalities yet, I’m just focusing on appearance for these portraits. c: I really really like drawing and coloring on this toned paper! I’ve been wanting some for a long time and I finally got it. Now I’m just waiting on my acrylic markers so I can put nice highlights on this type of paper for other projects!
