Hey there! I like how you captured Glen Keane's free-flowing quality and variation in weight. He's a great master to study especially for line. One thing to note as you learn off of his work is his use of construction lines. In this example, you can notice how he lays in guidelines around the face to capture the correct angle as it tilts backwards. He does this lightly, but it lays a solid foundation for the rest of the work to follow and gives insight into his process. Something to keep an eye out for in the future. Keep up the great work! :)

nice
