How to get curvier shape?

Hi, I'm wondering what exercises I should be doing to pull in the sides of my stomach in order to get a more desirable hourglass shape?

At the moment I'm doing alot of twisting situp type exercises twisting situps with feet on the floor, feet in the air, side situps with knees to one side on the floor (they are a killer) and full situps twisting to both sides once at the top of the situp, and also some work with weights - leaning to the side with dumbbell in one hand and using my side stomach muscles to get back to upright position. I also run 5km as part of my workout and try to do at least 20-30 mins on the crosstrainer. I workout 3times per wk.

I have seen a difference so far but I wondering if there was anymore i could do?

Stats about me incase you need to know:
Weight 110lbs/50kg/8st
Height 5'1"/155cm ish
Waist 24"
Hips 35"
Bust 34D/DD
Daily maintenance cal allowance - 1500 (mFP said 1590 but i've set it lower and seems to be working out fine)

I know im not too far away from the "perfect" ratio, my body shape might not allow me to get much further towards it which is fine. To me it seems like my waist needs to pull in a tiny bit more or my hips need to get bigger, If there are any exercises that make that happen please let me know although I really dont want my bottom to get any bigger, im quite happy with that how it is.

Thank you MFP-ers! I know you guys will give me some answers!
