Jaelithe,
I think I'm going to say a couple things you may not like. However, when I posted my picture for the first time, someone was hard on me and it has made a difference. (I'll post updated pictures soon...)
Things that would help more than posing...
1. Better make-up would help.
2. You have the basics of a really good, feminine body. Lose weight and work out for a more feminine shape.
Overall, not bad at all. I think you can pass. Your poses are getting there. You're off to a good start.
Hugs,
Jen
