Walk Cycle and Victorian Character

I’ve created this character and also rigged him from scratch. It’s the first time I have done a walk animation (after many attempts) and this is my latest version, but it still needs a bit of work.

I love Victorian ghost stories, so my plan is to make some low poly ghost stories with this character. I also plan to use flat shading - hence the outline of the mesh, although for clothes I might use smooth shading. – Any feedback on the walk cycle and model is appreciated.
