Help partial suspension, am I missing anything

[interestingname]

• 3/8'' polypropylene rope, safe working load of 225 lbs
• attached to support using a snuggle hitch
• slipknot for the noose
• place the knot on the back of my neck
• noose at the base of my neck
• bend my knees and let my body weight tighten the noose

does this look about right? I'm a bit nervous and feel like I'm forgetting something.

I am no expert, but this looks good to me.
