I decided to do this because I believe you have a lot of potentials and you seem to have an eager spirit to learn.
Don't let go of this outlook.
In this, you'll find a realistic example of the breakdown of the general shapes of the wolf, directional anatomy lines, and some pointers of what you did amazingly as well as some things you could improve!
Try using reference (yes, even for cartoons!)
I personally suggest Pinterest or google images.
I can't wait to see your upcoming works.
