Draw over the pencil lines you want to keep with a felt-tip pen. Erase the extra pencil lines, and the dinosaur is ready to color.
Your dinosaur is finished! Even if you don't get it right the first time, keep practicing until you're happy with your drawing.
Whether you are a fan of dinosaurs, a budding artist, or both, learning to draw dinosaurs is a lot of fun. Experiment with color and materials, and, most of all, practice. You might soon find you've brought dinosaurs back to life -- if only in your sketch book.
