This is a fabulous, fabulous piece. I love the collage aspect of it. It ties is in together. If it were any flatter, the drawing would become a bit dull, so I like how you can tell it has texture and rises above the background sheet.
The illustration is precious. Both of their innocent faces are beautiful. Although I feel like the orange in both of them blends a tiny bit too much. Like, when I glance at it, I thought she was riding the doe. But, it doesn't really matter since it's gorgeous anyway.
And that bit of a blue galaxy of stars drifting across it was a good design choice. Really draws your eye across the piece and around.
