I'll need more context then that. As in, who is Dawn (OC or something?), how she looks like, maybe some very short biography(what's her temper like, is there some relationship between characters etc) but not necessary.
Come to think of it it would be better to send this sort of requests\question\info via notes (or whatever the private messages are called around here) as to avoid clutter on the profile. And awkward public discussion of drawing ponies.
