Very cool! I like it, and I do feel movement. I also don't have a problem with the rightmost guy. I think, since am a person that sees, reads and (s)pans things from left to right, the fact that the runners are running from left to right might be aiding the feeling of movement implicitly.
Some minor things I noted or observed, feel free to ignore:
- The two figures have almost identical pose. Perhaps some variety?
- The legs are too thick at the base. Being runners, would they have more toned musculature?
- Some shadows might help like Trevor points out. Also, if you detach the shadow from the human body source, it will indicate a person in slightly mid air and might contribute to a feeling of movement.
- Lastly, sorry to hear about your challenge. Am glad you found a medium through which you can still pursue your love for art.
