Losing weight

Around June 7th I posted about working out but not seeing progress. It's way over a month later and I've lost 10-13 pounds compared to my first week!!!

I'm happy with my overall shape,

But I want my butt to look perkier and bigger (I'm trying to go for the hourglass figure). Does anyone have any tips?

I was also wondering if it would look weird (since I'm pretty petite and small chested) if I had a "big" butt?
