At the start, there was a tiny bit of light flicker, but that sorted itself out afterwards. The walking was a good but make sure that the chest piece is roughly in the same position throughout, as at one point he leant too far back and too far forwards. The other movements were good, but they were lacking the 'ease in, ease out' rule of movement. This is probably the best video on how to do it by Fancy Pants. For the part where the armoured guy jumps down, bear in mind that to achieve a realistic effect, your character should fall twice as far as the last frame due to the acceleration of gravity - yes, you have to use physics here - (checkout this video by ForlornCreature for a better explanation)
