Looking good, but hate to say this, the radiator louvres are not installed correctly ,they should rotate and the upper edge of each vane fits underneath the one above, on your set up you have four completely on top and three underneath, when they rotate the top ones will impact the lower ones and vice versa, think of a Venetian blind affair.
Here's a photo showing the vanes shut and you can see that they are all layered, like feathers or roof tiles.
Here's an oblique blow up which shows a little better how they overlap
Sorry to be a bearer of bad news, but you'd of found out one day, probably once it'd all been painted and you'd not be happy, given the amount of care and effort you've clearly put in so far.
