I like how they look as unit yet they are not uniformed - good choice of colours and shield transfers.
Also, victrix macedonians are not the usual suspects for hoplites, but they look great (more hellenistic helmets than in greek hoplites boxes).
32 warriors per unit would be 4 ranks 8 files? What rules are You planning to use?
As you said 8 files 4 ranks. Rules for Hail Caesar - frontage of units is standard so I use 8 files for all block units but usually 2 deep. For a phalanx I'm going for 4.
The hoplites represent individuals banding together for a fight, thus the lack of uniformity, besides being fun to do! Also I'm using a sort of colour coding - I never do green, red, blue and yellow in the same unit - it unsettles my mind!
The greek hoplites have corinthian helmets and hypaspists phrygian ones, so the successor kit gave me a lot of options on helmets.
