Rust Blocks beside Pale Curves

Rust-colored blocks sit beside pale sweeping curves, giving this abstract puzzle a clear split between oxidized metal and plaster. Scratches, edges and cast shadows add clues inside simple color fields.

Sort by shape first, since straight block edges and curved plaster boundaries rarely belong together. Follow a shadow back to its form, then use rust grain and pale surface tone for center pieces. Metal scratches run straight across some blocks, while plaster grain follows each pale curve. Cast shadows point back toward their blocks and keep pale curves from drifting into metal groups.
