T-M13,
No one here can give you any meaningful advice about your mechanics without seeing them.
My advice is: Get someone to videotape you (please ask them to use a tripod--please!) from 3rd base (if you are an RHP) or 1st base (LHP) and perhaps also from a frontal view.
Figure out how to post the video at this site for the coaches and pitchers to look at. You will get high quality comments, maybe some questions, etc, and the feedback will be meaningful.
Personally, I wouldn't be so open-minded as to accept advice about my mechanics from people who've never seen me deliver a pitch. They may have the best of intentions, but they will not be able to tell you anything important unless your written descriptions of your mechanics are (1) accurate accounts and (2) truly outstanding in their depth of detail.
If a single picture is worth 1000 words, what do you think a 30 second video clip might be worth?
P.S.--Seriously, don't make us all sea-sick...get your videotaper to use a tripod or some kind of firm support for your pitching video.
