Please stop saying "I will do that bit later". You can't just do legs, and then just do the arms, and then add a bounce, you'll end up with something looking very disjointed. Those elements of a walk cycle are all fundamental to each other and affect each other. The bounce affects the length of arms and legs, the legs affects the twist of the body, the arm swing affects the bounce of the stride.. you need to work on all three simultaneously for a good result - even if the arms/body are just outlined and coloured later, it is important in order to get the leg movement looking correct.
A good walk animation *is* difficult, slightly more so in iso at that size because you have limited pixels to use to show the perspective and angle of the body.
In its current state, its not too bad and has shown good progress. However, the legs look too separated from each other (thighs hardly move) and in isometric, the front thigh should cover more of the back thigh at certain points in the cycle. Also 90% of your leg movement is only in the bottom half of the legs as if his thighs are strapped together with a belt. Walk a few steps in front of a big mirror and watch your own legs moving. The waist also has no movement - when he bounces his chest therefore seems to stretch. There is no movement in the shoulders either. The whole body should twist ever so slightly during the walk. As the arm swings back, it pulls the shoulder with it slightly, making the opposite shoulder move forwards slightly (most of the effect of this is just down to shading and details on clothing, but the should shape is another part that helps reflect a slight twist.
