Vermilion Beneath an Ink Arch

Create a contemporary original ink-on-paper abstract painting: two broad fluid charcoal ink washes almost meet to form a loose arch over a vast blank rice-paper field. One tiny vermilion square sits below and slightly right of the opening. Visible fibers, organic water blooms, convincing brush pressure and natural feathered ink edges. Strong breathing space and confident restraint, no calligraphy, seal, text, frame or signature. Create exactly one finished image, aspect ratio 3:4. No collage or contact sheet. No watermark or signature. Keep all people original adults. Render at the native size available; do not add a frame.
