Looking great girl. I think your back is looking great, really work on your posing. It's too hard to tell what you may need to bring up until you get comfortable doing the poses. Overall back thickness is awesome, especially the lower back the deadlifting really shows. Looks like your leaning out well. On the posing just remember the three rules to it Practice, Practice, Practice. Best of wishes to on the rest of you training for the comp. If you need any questions answered just ask.
Cheers,
