Personally, I think you should jack up the size and growth of her boobs and her butt cheeks. The butt cheeks also look too deflated, taking away from her curvature (her back fat literally surpasses it.) One of the main appeals of fat women for most guys is the woman's boobs, butt, hips, and thighs growing bigger and softer (voluptuous, you know. To vision for reference, imagine an hourglass figure getting fatter) Other than that, it looks good! Wish you luck!
