That looks a neat job John, & the shape of the bags really suits the bike. What make of bag are they ?
The only thing I would say is keep a careful watch on your paintwork where the 'over straps' rest as it may abraid the paint finish in time. The only way around that is probably to fit a carrier rail (chrome or stainless) to each side as a 'bag fastener'.
This is not normally an issue with conventional roadster bikes as the 'throw over' style bags usually fit on the pillion seat where the straps have little direct contact with the paintwork - though there can be some issues with dulling of paint on the flanks of such bikes if the throw-overs are used regularly.
I suppose, at the end of the day, we should remember that throw overs are really designed for a temporary convenience - such as holiday touring. It goes back to the pros & cons of 'fixed' luggage.
I've used both types over the years, and each has its advantages.
