More than likely it's the equipment that is limiting you. Small diameter logs just suck to clean. I had a 9" log that I turned into a 12+" log, and simply increasing the diameter changed my technique with no conscious action on my part.
Here is my first time ever using the log, and I imagine my technique is similar to what you were talking about
And here was my first time trying out my ghetto log
So I'd say, don't beat yourself up too much over your cleans sucking, because it's just a nightmare to try to clean. BEFORE I increased the log diameter, I found some success in just REALLY exaggerating the lapping portion of the clean with the 9" log. Basically, row the log into your lap, sit WAY back/down, press the log into your chest, and then pop your hips up while you stand and try to roll the log up your chest.
Still get a video up when you can. It'd be good to see if there are other things that can be addressed.
