We are in the practice of performing complex movements, to be sure. However, don't let yourself get too 'lost in the sauce'. Ask yourself from time to time "what is the goal of this movement?". For example, a clean, in simplest terms, is getting a weight from the ground to the rack quickly. A pullup is getting you from a hang to head above the bar. When learning a new movement, take the time to define what it is you are learning before diving too deeply into technical minutia.
Once you know where you are headed, start cleaning things up. Focus on one or two things at a time. It does nothing to go into a complicated movement with 6 things on your brain...chances are, your attempt is over before you can think about all 6. Practice one element (heels down this time) until you can get it cold, then add in another element (chest up/better spine position)etc. Continue until you are solid. This takes time, but it is only when we are presented with a test of strength that we have only one chance to get it right. This is the art of practice. There is always another rep/set/training day, until they cart you away in a pine box.

Think first, shut that thing off and do!
