Sonic appears to be enjoying the ride on top of this colorful blue and white airplane. His arms are crossed casually and he has a determined look on his face as he takes in the view. The wings of the aircraft feature a bright yellow and black checkered pattern and there is the bold word "JET HAWK" written down the side of the body. It's a vivid and exciting image that definitely calls out to be colored. For the airplane, I would use different shades of blue and the yellow and black checkered pattern can be enhanced with small lighter and darkercolor variations. Sonic would look great in his signature blue fur, with a few hints of red or green accents if you want to spice it up a bit. Furthermore, the clouds and the scenery around could be colored with light and bright colors to give the picture an uplifting look.
