The firmness of the top breast in the top frame is baffling. I know that is what people want to see in comics but the bottom breast has the correct hang while the top doesn't so it confuses me greatly.
@Fantastic I was going to make the same comment. That breast is defying gravity. I know it's not the most attractive thing to have a breast be weighed down but in this case not doing it looks a bit bizarre. This rookie mistake is kind of surprising given how great the art normally is on this site.
Actually, considering the fact she's leaning backwards from the pov and has her arm atop the breasts I'd say that look would be fairly close to natural
