1. I didn't like the right ear position
2. the eyes were crooked.
Therefore I used the ear from the next photograph as the Leopard had flicked it forward, and alsoadjusted the eyes. The grid lines made this an easy task, they also enabled me to see that the nose and mouth would line up correctly.
I then painted the eyes in acrylic and started working the fur using a mixture of coloured pencil and acrylic.It is the scan that is crooked, not my lines!
