Pittbull bulldog, 
mid-tumble over a well-worn football, 
tongue lolling out in a wide grin, 
evening golden light casting elongated shadows, 
playful scene unfolding in a lush, 
green backyard, 
focus on gleeful expression, 
fur texture detailed, 
dynamic motion blur emphasizing playfulness, 
shallow depth of field with bokeh effect in background,

vibrant color palette, 
high resolution.
