Circle Drawing

I think this drawing turned out well. I like how the shape of the submarine turned out, but I do think I could have added more detail to it. I could have added the bullets in the front to the sides, but when I looked up drawings and pictures of submarines they didn't have that, and I wanted to make it as realistic as possible so I decided not to add that. Some things I think I did well were filling in the white spaces of the water. And creating a good color contrast. Some things I think I could improve on are adding a little more detail to the submarine, and finish coloring the inside of the submarine a darker grey.
