Bizarrely enough, even though this artist tends to focus a lot on breasts and a shapely body, I actually think in the original art Sena had a much larger chest and wider hips. Go figure.

I disagree somewhat. I think this artist focuses more on sexy apparel like bow_bras and making characters stand out in a sexy, feminine way. It's apparently enough for the artist to leave her chest at about the same volume as the fine ladies in his/her other drawings.

That said, I agree that Sena does have a larger chest and wider hips canonically, proportionally speaking.
