chickenkts - Good start. It would be nice to see darker darks in the scene, more blown-out white inside the pumpkin, and much softer shadows on the light coming out of the pumpkin.
fulg0re - Nice scene. It seems a little lacking in color, maybe if the key and fill on the background were two different colors there’d be more contrast and interest. Maybe more shadows could help break-up the back wall as well?
