Hamster Warrior, seeking critique

[insollence]

Hello there everybody ! I had to design a character that was fully or partially a Hamster, had a Yo-yo and had some kind of Hairstyle but besides that I got into digital painting and value study recently and wanted to know if I'm going in the right direction, the only references I used were for the Hamster head and Pectoral muscles.

Thanks in advance !
