“Your drawing is good” gets a smile. “The shading on the hands is crazy” gets remembered.

A specific compliment proves you looked. General praise is kind and could have been said from across the room without noticing anything, while naming the part somebody struggled with tells them the work was actually seen. That is also the part they are least sure about, which is why it lands where it does.

Find the detail next time instead of reaching for the easy line. Say which bar of the song or which corner of the drawing, even if you have no vocabulary for why it works. The vague version is forgotten by dinner and the specific one gets kept.
