I have attached a picture of an example lizardman army with 1 commander (unfortunately it is a bit blurry). I have tried to display several different formation types. the pterodactyls are in loose order, the big lizards are in close ranks and the skinks on the right are a rabble. the group immediately to the right of the coatle are forming a defensive knot around the wizard.
The drummer amongst the spearsmen is a more elite model with a higher command value. Along with the drum this should allow them to keep up with the bulk of the army however it is combinations like this that I want to check work in practice.
Below is the list showing how I chose the units, unfortunately I don't have any painted models for more complex units like war engines with crew.
