I have to admit, I was quick to post a reply to this without hearing a lot of your compositions. You are a virtuoso and I commend you for the beautiful music you have created. It would be wrong to suggest playing to a click, I know your music should flow naturally... If there's a common thing you do that you might want to consider breaking, it's the triplets. Maybe try not playing in triplets. When playing really fast and shifting to a different position, there's a pause... what if, instead of playing fast, play slower so that transitioning to a different position would sound seamless... Try going from fast to halftime too, that would be interesting. A user also suggested the use of other instruments in one of your posts... Lastly, if you are open to the idea of playing to a click, it won't hurt to try... and then, if you feel like it, wanna play audio tennis?? :D
