This is two versions of a portrait work. The first version I made is in a white background, and the creative inspiration is the image of the Swan Lake ballerina. After finishing it, I want to feel the effect of the dark background. So I cut the background and the white feathers with a knife, recolored and added details to get this result. For the first time, I tried to cut out all the works that were firmly adhered with glue, and changed the background. I was lucky to succeed in the challenge.
