Made my first sculpture but it looks weird. Any tips or thoughts??

Did the master studies on Glen Keane's work. I was confused about which part to study, eventually went for a complete study of his work. I think I didn't attempted the project correctly, as I continuously found myself making corrections for a specific line to be of the same weight as in the original work which led to unconfident lines. Varying line weight while making a confident line is still an issue for me to improve i think. Any advice would be highly welcomed.
