This is a follow on from my answer here. I took this photo of my belay and shared it on Facebook, where I friend of mine (A qualified climbing instructor) pulled me up on it as I'd made one or two minor mistakes. There is nothing "dangerous" here. It's just not 100% optimal from a safety point of view.
Probably worth noting this is UK trad ethics, I know other countries will often do this kind of set up differently. Hopefully the "issue" is global but I'm not an expert on non-uk belays so ¯\_(ツ)_/¯
Question
So the question is, can anyone pull me up on this belay stance? What (if anything) is wrong with this set up?
Additional information
The white arrows indicate the gear placements position (Trad placements in rock). the Black arrow is the load from the climber. The bottom carabiner is passed though both rope loops and attached to the second using a belay plate. I will stand to one side when belaying lining up the load between the gear and the second. Gear is placed above me and there is space to sit away from the rope so I'm not under any loaded ropes should a fall happen.
The bottom biner is not cross loaded, it's just not loaded at the moment so when the second starts climbing it will all pull straight. The HMS carbiner can take two knots easily.
