Looking good on the Scot. You might want to give some thought to the cover for the pipework to the top feed. Having built this kit (the thread was on RMweb years ago), it is worth thinking about. I don't think that my solution was brilliant...I used paper soaked in superglue. I did experiment but I'd try something different on the next one. Either that or I'd get the Brassmasters boiler - which includes this already cast onto the boiler. I might be mistaken about that, I'd have to fish my spare out if I can find it!
Geoff Brewin, before he passed, had designed and produced an upgraded chassis for the Scot in nickel silver, have a look at the Comet site as the chassis allows for it to be sprung...bit late I know, but worth thinking about for the next one. :-)
