the photo of the Boss behind the 2 Cobras under the window with a house visible outside. Great lighting and camera angle. I also like the mix of shots, some with all blue subjects and others with a mix of wild colors.

I did find a reference to ceiling mounted shoulder bests on the Boss 429 so that might be what they are. Link to a post with a photo

That Boss does look good in blue. Not sure whether it's the same blue used on my old budget Welly 302. The two look a little different to me.
