Janet didn't say anything about this enigmatic figure; an angel-boy holding a cross in folded wings. I think it might be a chalk or pastel drawing with some digital linework added, or perhaps entirely digital drawing.
One of the strengths of this piece is that while the drawing is very simple and almost abstract in parts, the actual proportions of the face and shoulders are accurate, which helps give the viewer confidence in the authenticity of the artist's vision. The wings are drawn simply - we don't need to have every feather detailed to know what they are - which leaves room for expression.
