Apollo line art Picture

So this is my rendition of apollo because two of his symbols is a snake and swan, so I am not finished with it I am thinking about how I should color it. But I think I should water color it, at the same time I wanna use digital art to color it because I can erase any mistakes. I wanted to say he was the god of fire, but then I had to correct myself because the god of fire is Helios.
