Brunswick Leib-Bataillon

I like the simplicity of the black Brunswickers who were described by one British officer as looking like a giant hearse.  

Here is my Leib-Bataillon shown in two half battalions advancing in line.  The lead half battalion is largely converted Esci Russians and RSM.  The rear half are mostly Hinton Hunt with some S Range.  Most are in the 1815 dolman but some are in the earlier Litewka.

The problem is achieving a sense of contrast with black uniforms, especially given that I put a gloss varnish on my figures.
