Last year I bought some lovely Middle Imperials from David Imrie, and recently, with great trepidation, I started to paint the few additional minis I required to complete the units.
I have expanded the units from David's 12cm frontage to 18cm, which is the size of unit I prefer for my 28mm gaming. In the sagittarii unit below, David's figures are the central five and my two are on the wings. Mine aren't as good as his but they work reasonably well together as a unit.
The second unit (below) are lanciarii. I only had three of David's minis, so painted the other four on the wings. Fortunately poor focus conceals the worst of my daubing. The base came out well; I extended David's original base with strips of card and matched the style.
I think I am possibly unique in terms of base size- I've not seen anyone else making such hulking great elements. I find that they really help with setting up games quickly. Since in my rules light units die on the first hit, there is no need for casualty removal! ;-) On these bases I've decreased the number of minis from my usual 9 to 7, which I think actually improves the look.
Finally, in the closeup you can see how much better painted David's mini (right) is than mine. But they will look the same from 18" away (or so I keep telling myself!).
