A really nice look at a quadraped walk cycle! Something to note is, even in live action reference, the shape based deformation and contrast in the legs are very visible. While there are some small joint bumps that don't make for a perfectly smooth line...simplify it! Look at the squash versus the stretch and how it runs throughout the entire leg, shoulder/hip muscles, and the neck (when referring to the front legs).
