It's fine to elaborate.
I like Amano's art because of its ethereal nature. The way he captures his subjects with only a few strokes of watercolour or a couple of charcoal lines is something beautiful, and there's a strong sense of delicacy even in his boldest paintings. There's a lot of detail, too, but not so much as to look fussy. Not many artists can capture the essence of dreaming, but Amano manages it really well.
