Learning to use a palette knife

The other night I attempted this angel tutorial from Angela Anderson using a palette knife. They are both on 6x8 mixed media paper using heavy body acrylics. It felt very awkward using the palette knife instead of a brush yet freeing at the same time. I will be trying this on a canvas panel soon with a different background color. Angels have long been a favorite theme of mine. Several angels decorate my house through stain glass, wood carvings, garden statues and jewelry.
