Transform this frame into a dramatic SEASON TRANSITION shot (Winter → Autumn), vertical 9:16. The bear rider "Misha" on his snowmobile is captured mid-descent, racing DOWNHILL from a snowy mountain slope into an autumn park. Split the scene diagonally across the frame as a seamless seasonal morph: the UPPER-LEFT portion is deep WINTER — swirling blizzard, flying snow, whiteout mountain slope, cold blue-white light, snow spray kicked up behind the snowmobile; the LOWER-RIGHT portion melts into AUTUMN — a golden park with bare dark trees, thick carpet of yellow, orange and red fallen leaves on bare ground (no snow), warm amber afternoon light. Right at the diagonal seam the snow dissolves into swirling autumn leaves in mid-air, snowflakes turning into leaves. The snowmobile and bear are positioned ON the boundary — front half entering the warm autumn side, rear half still in the cold winter blizzard. Strong sense of forward downhill speed: motion blur, low dynamic 3/4 action angle looking slightly down the slope, leaves and snow streaking past. Keep the bear character design, fur, goggles/outfit and the snowmobile exactly consistent with the original. Cinematic, high detail, sharp focus on the bear, energetic adventure mood.
