Run Cycles (Almost)

It has recently dawned on me that during this animation project, I am going to have to animate a run cycle. Given that fact that in my past endeavours into animation these were the one thing I could not do at all, and that in my recent artwork my anatomy has been pretty poor, I realised I should probably get some run-cycle practice done sometime. This is my practice run at doing a set of quick animated gifs of the cycle. The results were pretty shocking myself, but I practised making gifs out of a few frames, starting with a basic anatomical sketch (attemptedly):

Moving on to an improved sketch, with features roughly added in:

Which I drew a layer over each separate sketch layer to make a final lineart:

Which admittedly is pretty poor, so I thought, as the final product would have background and colour, perhaps fades to white or black could be used for dramatic / slowmotion effect, and if I were to use a backing track I could synchronise the music to the clip using these, so I tried making gifs with these transitions, being my final piece until I decide (if I ever want to return to these sketches) to add background and colour:

(Yes I really do need to work on this, i'm aware. Golly gee.)
