Your legs are the most important part of your grappling skills. They are stronger and bigger than your arms and the main reason legs are important in grappling is that they are your moving engine. No matter if you play top or bottom you can only move using your legs so put them in good use, try to roll more with your legs that your arms like 65/35.

Also check out that weird choke from the same position you just after you hip escape a bit to the underhook. More traditional options like armbars and back takes ofcourse are always there...
