You are getting wierd cylinder are you aware of this?Specially where the cylinder wrap around the bottom creating to much of a corner instead of a clean ellipse.

I am not sure if it just due to a leak of paying enough attention to cleaning your edge or if you would benefit from pratice making cylinder. To find out if you have some common cylinder issue i recommend you draw 10 or 20 cylinder just black and white no shading needed and drawing them as if the cylinder is made of glass.But the issue seem to be when you want to turn your two ellipse into a cylinder you don't know which part we would see and which part we wouldn't see so in away you have trouble to estimate where the plane of the cylinder start to curve away from your eye .

Don't forget to think about ramping up the difficulty if thing become to easy.I could give you advise as to how to do that but that should be pretty straight foward.
