Fitting looks excellent - hope they're not staying that colour though
One thing to remember though, if you fill those panniers, they're going to be heavy and will want to rotate inwards at the bottom - if you haven't done it, adding a support/resting bar shaped like this. |___________| (I've attached it using the number plate mountings before), so that each pannier supports the other, really helps solidify them when loaded.
Could you post a couple of side-on views? I'm fitting the same kit (although with the thinner panniers) to our Fazer 600 and it'd be good to see where you've positioned them - I'll be making up my own mountings.
