Sorry, that second pic is too small to see much that can help.
Seriously though, I don't see anything about the way you're tacked up that would make me think "OMG, this girl has no idea what she's doing, she needs a trainer bad" *rolls eyes*.
There are a couple of things done differently than I would do it, but that's only because it's preference, not a safety or comfort issue.
Oh, and Gssw, what you're thinking of is a keeper LOL. Some of those older saddles don't have them. I can't tell whether this one does or not...though I suspect not.
