Something tells me I'm gonna regret posting this...
All right, here's my stuffty sketch. And if a spot looks oddly bright, it probably is; I tried to touch this up and erase some unnecessary linework in Corel Paint Shop after scanning it, and Corel is not the greatest program to touch up pencil sketches. And for some reason the scanner cut off the very end of the tail, it's supposed to be rounded as well.
The basic expression I was aiming for was "worried".
This is Kristie, my changeling OC. She basically created her own identity in Ponyville instead of stealing another, and only absorbed what she needed to survive, and tried to spread harmony and understanding as best she could. Then word gets out that someone in town is a changeling, some sort of royal inquisitor comes in, something like a witch-hunt starts, and Kristie comes clean because she doesn't want anyone else to get hurt. The inquisitor is going to take her away to who-knows-where when the entire town defends her, remembering the nice things she did for them. The inquisitor leaves because he can't do his job, and a valuable lesson on friendship is learned (Kristie hid her true identity because she feared how the town would react, which made the problem worse).
Any thoughts?
