Very good walking cycle, the viewpoint is perfect, the arms may need to be adjusted a bit since they seem a bit stiff and awkward. His head overall looks also very still like if he doesn't have movement for it, feel free to think about the eyes as-well, could he be looking at something? But seems good for the size of the head, also after watching the feet go back and forth for a few minutes, I noticed that they may need to be altered a little bit, just a small tweak, since the right foot in the background looks slightly unnatural when touching the ground, due to a sort of two-dimensional look of it. On a side note, great job, can't wait to see if you'll upload another animation test so others can give their thoughts.
