6 Crows in 5 Panels, Acrylic. 5 3x3 panels

This is my entry in The Oregon Society of Artists July show - Extreme Paintings - extreme in size that is. The show reception is July 8th, 1pm to 4pm. This is only my second acrylic painting. The under-painting is dark red, the background is metallic gold and the crows are black silhouettes. The price of all 5 panels is $100 or buy each panel separately at $20 each. Hum, is this a diptych plus a triptych? Not sure what 5-fold is called in Greek. Do you?
