This was a gift for my mom. Both of my siblings occasionally create artwork, so I found a reference image of the same rose for us each to draw in our own styles. I’m mixed media, my brother makes insanely tiny, detailed line drawings (usually digital), and my sister creates still life in oil pastel. I mounted each drawing to the same size wood panel then mounted in a custom slotted frame, which is why the stem (and my signature) are a little above the bottom edge.
If I were to do this again, I would require we all use the same colors to further highlight the style differences.
