You are starting with your butt a little too low and pushing the bar forward a bit. A slightly wider grip would not hurt anything, either. Besides that, however, you are not really doing anything terribly wrong. You are just moving very slowly. That is why this is difficult. Watch the video below and note the speed at which the trainees execute the jump. The clean must be done quickly.

Also, the cleans will get easier as your deadlift improves.
