Step 15 (optional): For a cleaner look, erase as much as you can of the initial guide lines. Don't worry about erasing all of the guides. It's okay to leave some behind. Also re-draw any final sketch lines that you may have accidentally erased.
Final Step (optional): Add a few lines within the bee's wing for extra detail and the legs on the other side for structure. The wing is mainly see-through, so don't worry about making the shapes inside perfect. You can add the bee's legs on the other side for further structure. Don't add too much detail to them.
Add some shading to your bee drawing to give it more dimension and volume. Pick the direction of the light source when shading so that the shadows are consistent with it. Don't make the shading too smooth. The rough edges indicate the bee's hairy body. Vary the pressure on your pencil to get different degrees of tonal value.
Add a cast shadow underneath. This helps ground the bee so it doesn't appear to be floating.
You can add more value throughout your bee drawing for extra detail. Don't make the added value too smooth. The rough, textured value gives the bee a fuzzy appearance. Alternate between a dark value and a light value in the abdomen to give the bee the classic stripes. It's always a good idea to use reference for accuracy, and remember to pause the "How to Draw a Bee" video any time you need help along the way.
