And when practicing DO NOT ever stutter step. Also do not ever mount your bike when practicing in any other style except the proper mount. One drill you can do is get a length of field that is a nice flat 50 meteres or so. Run a few steps and mount then immediately dismount (properly of course) and repeat over and over. Proper cross technique requires a lot of practice because what you are doing is training muscle memory. You cannot think properly in a cross race so you need to rely on muscle memory and that only comes from practice.
