Whilst I'm trying to be helpful (but probably failing):
Power supply to the bench grinder and drill. Wouldn't the cables come in down a conduit rather than being chased into the wall?
If you had an electricity supply, wouldn't you want a light on the workbench?
No broom to clean up all the swarf?
Don't get me wrong - this all looks fabulous already and is WAAAAY better than I could ever achieve. I particularly love the way you make your dioramas look busy and include everyday items that quietly increase the realism without looking contrived.
