to be sure... I love boobs
I like your lines and curves. You draw well, and I envy your ability to put image to paper.
I'm personally not a fan of overly large breasts, but that's my preference. I wouldn't turn those breasts away from my hands
If it's critique you want, I'd soften the lines around the areolas and breasts. Boobs are less ball-shaped and more soft. The breasts you drew look like they are implants and have stuck-on areolas. Soften those lines and give a hint of irregular shape
