this is where he signs that picture 99% of the time.
The one in the OP is horrible. It tries to replicate the typical up slant "c" that is sometimes present. If you study the one on this pic and compare it to the others you are looking at it, it might help you in the future.
When I look at your pic, in 1 second I say what a "piece of shit".
When I look at the real thing in 1 second I say, "what a beauty"
Good Luck!!!!
