Handspring help??

I've been trying for the past 6months to get the handspring. I finally, FINALLY was able to do it the other day. I'm unable to load the video from my phone so here is the link: http://www.facebook.com/home.php#!/photo.php?v=342850179150267&set=vb.488033484572352&type=3&theater ;   My only problem is that I cannot always get it and I fall out of it when I'm trying to push upwards like my beginning attempt in the video above. I was wondering if that will become less frequent with practice or if I was doing something wrong that you girls/guys could correct. Also is there another way to do this a little more gracefully. I have tried to do the handspring where you swing your outside leg in a large circle and I'm currently unable to get my hips to rotate into position. I can get myself up high, like REALLY high but I don't have the core/oblique strength to stop, hold, or rotate at the moment.
