A trick I learned from another (non-aikido related) forum....
Take a short video of yourself
Post it on youtube
Include the link in this thread
That way, we can all see, and the chances of offering helpful advise increases. Just a thought.
If you decide to post something on YouTube, I would also advise you to disable comments and "show links" option.
It's hard to add any other input without watching what exactly you're doing...
