Step 5: Inside the circle, close to the right edge, lightly sketch a small circle for the angelfish's eye. When you get the position and size of the eye right, darken the shape. Inside the eye, draw a smaller circle and shade it in for the pupil. Draw a couple of curved lines around the eye for a few creases on the skin.
Step 6: Use the angled line on the right side as a guide to draw the angelfish's mouth. Darken the top edge of the guide but angle the line inward to create the mouth. Darken the bottom edge of the guide for the bottom part of the mouth. At the tip, draw a couple of short, curved lines for the open mouth.
Step 7: Darken the top, right side of the guides to create the angelfish's head. Dip the line down before the mouth. Darken the bottom guides but curve the line in and up to create the gill cover.
Step 8: Use the big triangular shape on top of the body as a guide to draw the angelfish's dorsal fin. Darken the basic path of the guide but make the line more wavy for a more organic feel. Curve the right edge of the fin inward. Inside the shape, add a series of lines to give the fin more structure.
Step 9: Use the big triangular shape on the bottom as a guide to draw the angelfish's anal fin the same way. Follow basic path of the guide but make the shape more wavy. Extend the bottom tip more and make it pointy. Inside the shape, draw a series of sloping lines to give the fin more structure.
