>>31351661The title is "Haruka shading reference".
The text pointing to her chest on the left says "ムネカゲこれくらいで" which means "about this much chest shading".
The text pointing to her chest on the right says "カゲつけすぎムネが大きく見えないように", which I think means that there's "too much shading added so you can't see her chest".
The text underneath each drawing says "correct amount of chest shading" and "wrong amount of chest shading", respectively.
Your assumption looks right to me, OP.
