noun
artistic taste; aptitude for painting; ability to appreciate art

彼は絵心があって、スケッチがとても上手だ。
He has an artistic eye and is very good at sketching.
私は絵心がないので、美術館に行
I have no artistic sense, so even when I go to an art museum I don't really get it.
noun

美しい風景を見て、急に絵心が湧いてきた。
Seeing the beautiful scenery, I suddenly felt the urge to paint.
