After getting to this stage I wasn't happy, I wanted him to be less egg like than most of the Humpty reference I looked at although still maintain the cliche. As said, I really didn't like this face and punched him in the face and started again....
Next up I began sculpting the hands and feet here are some in-progress shots, During this time I started thinking more about the back story of the character, the original rhyme was apparently inspired a Siege engine used unsuccessfully to approach the walls of the Parliamentary held city of Gloucester in 1643 during the Siege of Gloucester in the English Civil War.
Thank you for all the replies and kind words! I hope to upload pictures from my next model very soon!
Ps. Cheers for the advice egerie, I tried uploading a picture to the original post but it hasn't changed the thumbnail, am I missing something? anyone who can explain how to change the thumb would be a great help!
