Can I get a redline on the tits? it just don't look right, I've watched so many guides, and it just ends up looking unbalanced, I try to make it look like it connects into the shoulder diagonally like a teardrop but it looks weird. I've never been good at suggesting organic form with lines but this is especially frustrating

Other advice welcome as well. How are the proportions? I calculated and measured the body type that I jerk off to the most and after a few hours of drawing and testing I came up with this. Beautiful, isn't it? 3D girls can't compete.
