Good attempt, don't get discouraged, you are making progress :) There are indeed some things to solve, here is a drawing how I would approach them. Generaly if you feel that you are missing asomething, try to look for reference, for this character, a human pig mask, and sumo fighter is a nice support for the idea yoou have. In your version head is flatten too much, like it is seen in diffrent perspective, that whole body is. You have a base idea for torso, but legs should be studied more by you. Keep drawing, and you will get better!
I see, thank you for your help <3
