Emma Roux is an artiste designer based in France who loves to work with acrylic on plexiglas. I love her use of bright, vivid colors, and the way she put silhouettes and illustrations together to make gorgeous artworks like the above pieces. She also produces some design works, such as chairs, tables, mirrors, decoration murals and desk. I heart the chairs!
Her site has its english version, but I couldn't browse it due to some technical errors (browsing/downloading errors, perhaps). If you had the same problem as mine, just browse through its French version. It works just fine.
