Your scratchbuilt rendition looks absolutely great, Belg.
This is one HO kit I did spring for after seeing B.T.S.'s diorama at a show in November. The mfgr. does include a good amount of detail parts in the kit, including brass figures. Either approach works; it's the fun along the way and the satisfaction you get from building that matter. I will note that there have been a couple of my scratch projects that got a bit out of hand--I spent more on doors, windows, and details than the kit would have cost in the first place!
Please keep posting those photos Belg! Happy Easter.
