It isn't a pixel, but it has gotten really better!!
The first few you did were pretty good. if you use the pencil, and stay along the edges of the body when you are drawing, (zoom up, too! It helps!) It will look even better! And Blue's right. It would be even better with the shading, too!
If you want me to, I can help you out! I can give you useful tips and stuff! Just PM me! :D
