All right, I think I finally know what kind of pony I want...
Gender: Female
Type: Pegasus
Coat color: A very very light tint of the mane color, almost white
Mane color and style: The teal-ish color from my current avatar's clothing with short hair (something like Scootaloo's but not necessarily sticking up so much)
Eye color: Yellow or gold
Cutie mark: A
spearhead with the red tassel and maybe part of the wooden shaft as well as the actual silver spearhead. Maybe a darker shade of red that doesn't stand out so much against the teal colors.
Pose: Walking towards the left but turned back towards the right, dragging a staff in its mouth that trails on the ground (long enough that it extends outside of the avatar box, if necessary). (No actual ground or trail, just the action of doing so.) Wings open, even though she's standing on the ground with no intention of taking off.
Expressions: Happy
Accessories or costumes: Staff as mentioned, similar to current avatar
Thanks to whoever does this
