This fireman looks like he is ready to put out any fire! His red suit and red helmet contrast nicely with the red fire truck he is standing in front of. I think you could make this picture really stand out by giving his suit and helmet a bright, glossy look, while shading the fire truck for a more realistic effect. You could also use lighter shades of red for the axe in his hand. To give it an even brighter look, you could make the background a vibrant yellow and create a cheerful, glowing atmosphere around the page. Finally, you could add a few touches of white for highlights – maybe for the fireman's belt or for the edges of the fire truck. Let your imagination flow and have fun!
