I got the final okay on this order just today and except for some clean-up on the bases (that I noticed in the photos) it's ready to go out.
This is the first time I've done a squad or unit to a mixed quality. In this case the Inquisitor was painted to the "Tabletop" standard* and the retinue was painted to "Gaming" standard. Shared colours, the excellent bases the client provided, and a unified theme managed to bring these models together though and I'm happy with the results.
*Note to self: replace the "tabletop" and "gaming" mumbo-jumbo with "Tier 1" and "Tier 2" -- it's makes just as little sense but it's easier to keep straight.
