Unlike the above people, I'm not bothered as much by the fact that you used a grab to perform decap, however I do mind that you made it really obvious. Grabbing at the last second will make it look a little smoother, and if you decide to hold on to his head, relax your arm after the decap for a bit so that your hand isn't as close to his head and then swing it forward to grab it. This will create a really neat illusion but is difficult to smoothly add into the replay.
